Arcam alpha: Added Cup R wheel

Alloy wheel weight is very important to the [http://en.wikipedia.org/wiki/Unsprung_weight unsprung weight] of the car.

Stuck on what PCD or Centrebore means, [http://en.wikipedia.org/wiki/Wheel_sizing read here].

If you want different wheels then listed below, you don't need pcd converting wheel-spacers like [http://www.eliseparts.com/shop/index.php?main_page=product_info&cPath=165&products_id=219 Hubcentric Wheel Adaptors.] as 4x100pcd is already relatively common.

What you need is simple wheel spacers in 4x100pcd, centre bore 56.6 to make the offset a little more common. These spacers would fit Vauxhall Corsa, Astra F&G, Tigra, Vectra + Opel Ascona and are therefore pretty easy to come by and quite cheap. [http://www.performancefx.net/wsvauxhall.htm example of cheap spacers]

To fit S2 Exige wheels or 111R wheels onto a K-engined Elise the fronts are the same, but the rears require 20mm each side spacers to correct the offset.

Brake discs

2015-08-22T13:56:15Z

Arcam alpha: /* EliseParts.com */

==Lotus OEM Fitment==
===S1 Elise===
====MMC====
When originally conceived and released, the Elise was supplied with Metal Matrix Composite (MMC) brake discs in combination with specific MMC brake pads. In general it is agreed that an MMC brake setup provides excellent brake performance and feel. The only real complaint seems to be that in wet weather the initial bite and performance is poor until the discs are dried by application. (From VIN 2260 a splash guard was introduced to reduce this problem - Source [http://www.elises.co.uk elises.co.uk])

MMC's differ from normal 'iron' discs in that the friction generated is mostly Adherent Friction rather than abrasive friction (a very good article on the nature of braking can be found [http://www.stoptech.com/tech_info/wp_warped_brakedisk.shtml here]). Essentially when the disc and pad come in contact some of the pad material transfers onto the disc surface, meaning the contact patches between the two are effectively the same material. As the disc rotates the bonds between the surfaces break and reform creating friction.

One of the benefits of Adherent Friction is that under normal use the discs last a very very long time. When braking the pads transfer their material to the surface of the disc, and it is this layer that is broken down, not the disc suface. Therefore the discs suffer very little wear. Under very heavy use however, the bonds between the pad and disc cannot reform as fast as they are broken down, meaning areas of the disc can lose the material layer entirely. When this happens the abrasive friction of the pad can score away the disc surface making it too rough to rebuild the original material layer. If this happens braking performance from the disc is permanently damaged and the disc must be replaced. For this reason car used on track or running semi-slick tyres may wish to use traditional setups.

MMC discs were also extremely light, reducing the unsprung weight of each wheel.

MMC brake systems were supplied up until VIN 3714, when increased part costs forced Lotus to introduce standard iron brake discs. Recently Lotus have had trouble sourcing replacement pads, and have offered discounted conversions to iron discs for affected customers. Third party replacement pads are available from [http://www.eliseparts.com Elise Parts] and [http://www.elise-shop.com Elise Shop]. These alternative pads are also said to improve wet weather performance. MMC discs are no longer available.

====Standard cast iron====
These discs followed the MMC disc as the standard brake disc for the S1 Elise from VIN 3715.

Although introduced for cost reasons, Iron disks are better able to withstand the high temperatures associated with track driving and provide better wet weather performance than the previous MMC disks.

The surface of the disks are solid, however they are internally vented to aid cooling. As the disk rotates at speed, centrifugal forces act on the air inside the vanes, forcing it outwards from the center. This action then draws fresh, cooler, air from the center of the disc through the internal vanes and out through the holes in the edges. (Lotus Part Number: A111J0128F)

[[Image:A111J0128F.JPG|thumb|left|Vented S1 OEM Disc]]
{{clr}}

====Cross drilled====
The Sport 135, Sport 160, Sport 190 and 111S models were supplied with iron disks which were vented and cross drilled. Cross drilling is the name given to drilling holes through the disc. This has a number of advantages:
* The holes allow for better cooling by drawing more air into the internal vanes.
* The edges of the holes clean pad surface which can provide increased brake 'bite'.
* The holes prevent gasses from collecting between the pad and disc surface
* The holes reduce the weight of the disk, and therefore its inertia and the unsprung weight.

(Lotus Part Number: A111J0141F)

[[Image:A111J0141F.JPG|thumb|left|Cross drilled and Vented S1 Disc]]
{{clr}}

===S1 Exige, 340R===
The Lotus Series 1 Exige and 340R, were fitted with the same cross drilled disks as seen on the Series 1 111s and Sport 160 editions described above.
(Lotus Part Number:A111J0141F)

===S2 Elise and Exige===
Series 2 Elises are fitted with 288mm vented iron discs.

The discs on the S2 are different from those one the S1. This is due to the S1 iron discs being a copy of the original MMC discs and therefore an uncoventional size. S2's were shipped as standard with plain discs, with cross drilled versions being available as an option. Later S2's were shipped with the cross drilled discs as standard.

The S2 discs feature longer, curved internal flow passages which increase the disc stability and reduce hot spot formation. The revised hole pattern has been specified to complement the new vane arrangement.

The discs are not handed, so the same disc is used on the right and left hand sides of the car. The cooling air flow through the left and right discs is identical and the flow rate is purely a result of pressure differential between the centre of the disc and its rim; the shape of the vanes and the direction of rotation does not affect the flow rate significantly.

Some noise from the brakes themselves is to be expected but there is a fix to stop brake pads banging in the calipers.

===Vauxhall VX220/Opel Speedster===

VX/Speedster discs are also 288mm as on the S2, but there are some differences:

* hubs are 5 stud
* use a bigger center bore
* use a slightly different offset (about 1 to 2mm) because the VX220 uses a different bearing pack. (uprights are identical to the S2 though)
* are almost the same thickness as S2 discs (25mm vs. 26mm), but have a much thicker surface and as a result a much smaller air-gap between the disc surfaces.

The last point makes the VX220 discs significantly heavier than S2 discs (around 750G to 1 Kg each).

The thicker surface should give them a little more heat capacity, but also makes it more difficult for them to shed the heat again.

VX220 discs are actually taken from existing GM cars (Vauxhall/SAAB), eg. Vauxhall Vectra V6 2.5 front discs, and as such they can be obtain from many regular car-parts stores are very low prices.

Wide aperture grooves

Dimple hole construction
Balanced geometry

The wide slot draws cool air across the pad surface keeping pads and discs cooler. They also expel dust, dirt and hot gases better than fine slots which eventually fill with rust and scale. 
The blind drilled holes are there to break down surface gases when braking hard from speed but do not weaken the cross section of the disc as can happen with discs that are drilled all the way through, thereby lessening the chance of the discs cracking due to heavy use. 
These discs are standard size OEM replacements with a cosmetic surface coating that helps prevent unsightly rust, however the coating will soon go and the un-braked surfaces of the disc will rust. 
The grooved and drilled design means the pads and disks run cooler but the surface area reduction means braking efficiency will be reduced unless the brake pads are upgraded to a higher friction compound to compensate. So if you add extra friction to better cooling you will have better brakes. 
Extra benefits of drilled and grooved discs is the effect the slots have on maintaining a flat smooth pad surface during the pads wear life. The slots encourage the pads to wear with a more flat pattern and the "Ribbing" common with non slotted rotors does not appear. This removes the "Record groove" effect of pads on plain discs, particularly around the outer edge and helps pads maintain better contact area with the disk through their life.

EBC Ultimax discs offer much quieter braking and feature a special paint process to prevent corrosion. Note that the black surface will go away on the part where the brake pads touch the disc and this area can/will rust. How fast is depending on how the discs are used (and brake pads). I have read reports from 2 month to still being totally black after 2 years.

==Common Questions==

===Pads sticking to the disc===

The unservoed brakes on the S1 were criticized for not having enough initial bite when first applied, so Lotus used higher "grab" pads on the S2 to improve this. A byproduct of these pads is they tend to stick to the disc over a period of time, in damp or humid conditions this can happen within a couple of hours. This is something that affects the S1 as well but not to the same extent. Normally the sticking is limited to a clunk on pulling away, but with wet weather or if the car has recently been washed, the sticking can be quite severe. This however is not a problem its just something you just need to be aware of, it is also just another case of [http://wiki.seloc.org/index.php/TADTS TADTS]

Brake discs

Arcam alpha: /* EliseParts.com */

==Lotus OEM Fitment==
===S1 Elise===
====MMC====
When originally conceived and released, the Elise was supplied with Metal Matrix Composite (MMC) brake discs in combination with specific MMC brake pads. In general it is agreed that an MMC brake setup provides excellent brake performance and feel. The only real complaint seems to be that in wet weather the initial bite and performance is poor until the discs are dried by application. (From VIN 2260 a splash guard was introduced to reduce this problem - Source [http://www.elises.co.uk elises.co.uk])

MMC's differ from normal 'iron' discs in that the friction generated is mostly Adherent Friction rather than abrasive friction (a very good article on the nature of braking can be found [http://www.stoptech.com/tech_info/wp_warped_brakedisk.shtml here]). Essentially when the disc and pad come in contact some of the pad material transfers onto the disc surface, meaning the contact patches between the two are effectively the same material. As the disc rotates the bonds between the surfaces break and reform creating friction.

One of the benefits of Adherent Friction is that under normal use the discs last a very very long time. When braking the pads transfer their material to the surface of the disc, and it is this layer that is broken down, not the disc suface. Therefore the discs suffer very little wear. Under very heavy use however, the bonds between the pad and disc cannot reform as fast as they are broken down, meaning areas of the disc can lose the material layer entirely. When this happens the abrasive friction of the pad can score away the disc surface making it too rough to rebuild the original material layer. If this happens braking performance from the disc is permanently damaged and the disc must be replaced. For this reason car used on track or running semi-slick tyres may wish to use traditional setups.

MMC discs were also extremely light, reducing the unsprung weight of each wheel.

MMC brake systems were supplied up until VIN 3714, when increased part costs forced Lotus to introduce standard iron brake discs. Recently Lotus have had trouble sourcing replacement pads, and have offered discounted conversions to iron discs for affected customers. Third party replacement pads are available from [http://www.eliseparts.com Elise Parts] and [http://www.elise-shop.com Elise Shop]. These alternative pads are also said to improve wet weather performance. MMC discs are no longer available.

====Standard cast iron====
These discs followed the MMC disc as the standard brake disc for the S1 Elise from VIN 3715.

Although introduced for cost reasons, Iron disks are better able to withstand the high temperatures associated with track driving and provide better wet weather performance than the previous MMC disks.

The surface of the disks are solid, however they are internally vented to aid cooling. As the disk rotates at speed, centrifugal forces act on the air inside the vanes, forcing it outwards from the center. This action then draws fresh, cooler, air from the center of the disc through the internal vanes and out through the holes in the edges. (Lotus Part Number: A111J0128F)

[[Image:A111J0128F.JPG|thumb|left|Vented S1 OEM Disc]]
{{clr}}

====Cross drilled====
The Sport 135, Sport 160, Sport 190 and 111S models were supplied with iron disks which were vented and cross drilled. Cross drilling is the name given to drilling holes through the disc. This has a number of advantages:
* The holes allow for better cooling by drawing more air into the internal vanes.
* The edges of the holes clean pad surface which can provide increased brake 'bite'.
* The holes prevent gasses from collecting between the pad and disc surface
* The holes reduce the weight of the disk, and therefore its inertia and the unsprung weight.

(Lotus Part Number: A111J0141F)

[[Image:A111J0141F.JPG|thumb|left|Cross drilled and Vented S1 Disc]]
{{clr}}

===S1 Exige, 340R===
The Lotus Series 1 Exige and 340R, were fitted with the same cross drilled disks as seen on the Series 1 111s and Sport 160 editions described above.
(Lotus Part Number:A111J0141F)

===S2 Elise and Exige===
Series 2 Elises are fitted with 288mm vented iron discs.

The discs on the S2 are different from those one the S1. This is due to the S1 iron discs being a copy of the original MMC discs and therefore an uncoventional size. S2's were shipped as standard with plain discs, with cross drilled versions being available as an option. Later S2's were shipped with the cross drilled discs as standard.

The S2 discs feature longer, curved internal flow passages which increase the disc stability and reduce hot spot formation. The revised hole pattern has been specified to complement the new vane arrangement.

The discs are not handed, so the same disc is used on the right and left hand sides of the car. The cooling air flow through the left and right discs is identical and the flow rate is purely a result of pressure differential between the centre of the disc and its rim; the shape of the vanes and the direction of rotation does not affect the flow rate significantly.

Some noise from the brakes themselves is to be expected but there is a fix to stop brake pads banging in the calipers.

===Vauxhall VX220/Opel Speedster===

VX/Speedster discs are also 288mm as on the S2, but there are some differences:

* hubs are 5 stud
* use a bigger center bore
* use a slightly different offset (about 1 to 2mm) because the VX220 uses a different bearing pack. (uprights are identical to the S2 though)
* are almost the same thickness as S2 discs (25mm vs. 26mm), but have a much thicker surface and as a result a much smaller air-gap between the disc surfaces.

The last point makes the VX220 discs significantly heavier than S2 discs (around 750G to 1 Kg each).

The thicker surface should give them a little more heat capacity, but also makes it more difficult for them to shed the heat again.

VX220 discs are actually taken from existing GM cars (Vauxhall/SAAB), eg. Vauxhall Vectra V6 2.5 front discs, and as such they can be obtain from many regular car-parts stores are very low prices.

S2 Wheel Options

2015-08-18T17:27:46Z

Arcam alpha:

Alloy wheel weight is very important to the [http://en.wikipedia.org/wiki/Unsprung_weight unsprung weight] of the car.

Stuck on what PCD or Centrebore means, [http://en.wikipedia.org/wiki/Wheel_sizing read here].

If you want different wheels then listed below, you don't need pcd converting wheel-spacers like [http://www.eliseparts.com/shop/index.php?main_page=product_info&cPath=165&products_id=219 Hubcentric Wheel Adaptors.] as 4x100pcd is already relatively common.

What you need is simple wheel spacers in 4x100pcd, centre bore 56.6 to make the offset a little more common. These spacers would fit Vauxhall Corsa, Astra F&G, Tigra, Vectra + Opel Ascona and are therefore pretty easy to come by and quite cheap. [http://www.performancefx.net/wsvauxhall.htm example of cheap spacers]

To fit S2 Exige wheels or 111R wheels onto a K-engined Elise the fronts are the same, but the rears require 20mm each side spacers to correct the offset.

Arcam alpha: /* Toe-in / Toe-out */

====Chassis development…or why is everybody telling me to get my car ‘Geo’d’?====
So you bought yourself a nice, shiny Elise or Exige,
and have driven the first couple of thousand miles?
That’s the point where lots of owners are hit by the
‘go faster blues’ and either start investing in go
faster parts, or walk away not knowing where to
start.

In this article, I’d like to give some insights to the
updates you can do to get more fun out of your car
without the need to install a 200+bhp engine for
starters.

One of the regular remarks on the forum is ‘get
yourself upgraded’. Of course, driving and racing
courses will make you go faster! Everyone who’s
even a little active within the Seloc community
knows the name Andrew Walsh (aka Walshy). He
can sure help you to understand your car and make
you go faster. Besides - it’s great fun to do!

Time to go for the first engine mod? Run out of
possibilities to go any faster? Not quite! There are
more possibilities to make you go faster without
the need to improve the power output of your car’s
engine. The trickery which makes this possible is
Geometry. I can hear people say ‘Lotus is the best
chassis developer in the world, so why would I fiddle
around with their settings?’ The answer is as
easy as it is logical - Lotus has created a car which
needs to be everyone’s friend. It needs to be entertaining
for the beginner but at the same time Lotus
wouldn’t want to make its handling tricky. If you’re
a bit further down the line, have built up track
experience and have some training courses under
your belt, you might opt for a bit more entertainment,
so you could start playing with the geometry
of your car. Before doing that, I’d advise you to buy
your first upgrade: a stiffer and adjustable front
anti-roll bar. This simple and relatively cheap
upgrade will enable you to play around with the
balance between under- and over-steer. (understeer,
in which the car starts sliding over its front
wheels while entering a corner; over-steer, in
which the rear of the car attempts to overtake the
front, ultimately resulting in a spin).

Mind you, the balancing act of the anti roll bar
(ARB) will not improve grip. A lot of people hate
under-steer and prefer over-steer as long as it’s
controllable. Control is exactly what you can get by
setting up the ARB. Another effect of this device is
the reduction of body roll - that does improve grip!
How does grip work? When you think of the four
patches of rubber which are the contact of the car
with the road surface, you can appreciate the basic
grip of the tyre. The more sticky the tyre, the more
grip you will have. Well not exactly - another thing
you wouldn’t want is to lose the weight on one of
these patches. If you do, that specific tyre will not
be able to provide you with the grip you’re used to.
Getting back to the ARB, body roll actually is moving
the weight on to the tyres. If you steer into a
corner, the mass of your car will want to move on
in a straight line. This will cause the body to roll
over the car’s roll centre. The less the body is able
to roll, the more weight you will keep in the same
place, so there you go - it will produce more grip in
a corner and will help you to go faster!
The next step to improve your feeling with the car
could be to start fiddling with the Geometry of the
car. To do so, you’ll have to understand the basics
of Geometry. If you really want to understand what
you’re doing and even want to do it yourself, I
would strongly suggest you pick up the parts manual
first and buy yourself a pile of shims. You will
need them!

First, the basics. There are a couple of things you’ll need to understand first - All settings are measured per axle!

==Toe-in / Toe-out==
[[Image:Chassis_development_toe.png|frame|right]]
Looking on the axle from above, if the fronts of the
wheels are closer to each other then the rears, this
is called Toe-in. If the opposite is true, e.g. the rear
side of the wheels are closer to each other then the
fronts, this is called Toe-out.

Toe-in will produce high-speed straight line stability
but will make the car a slow turner. You have
to work harder to get into corners.

Toe-out will not help you for straight line stability.
The car will be pretty nervous, but it will want to
attack each and every corner.
There is no such thing as the perfect setting for
Toe-in / Toe-out. The ideal setting for a (semi)-professional
race car driver might be horrible for you.
Keep in mind, the more toe you set, the harder
your tyres will wear!

==Camber==
[[Image:Chassis_development_camber.png|frame|right]]
You will now have to look at the wheel from the
front or the rear. The camber can be called negative
if the top of the wheels are closer to each other
than the bottom.

Positive camber is the setting where the bottom of
the wheels are closer to each other than the top.

Where camber is concerned nearly every possible
setting, the camber will be negative. The only
question is.. how far should you go?
The effect of negative camber might be loss of
straight-line grip. As you’re setting the surface of
the tyre in an angle to the surface of the road, you
are losing grip. But as soon as you enter a corner
(which is the place where you lose most speed
when track- driving), the surface of the tyre will
deform and, when your setup would be 0 Camber,
you’ll lose grip. Having the car set with negative
camber, the road surface contact will actually
increase in the corner, thus improving grip. Exactly
what you want!

==Castor==
[[Image:Chassis_development_castor.png|frame|left]]
This one is a little more difficult
to explain.. You will
have to look at the wheel
from the side. The hub is
behind the wheel and if you
look at it, you will see that
there's an angle between
the top and bottom connection
of the wishbones. This angle is called Castor.
Castor is controlled by shims at the connection
points of the upper front wishbone.

If the castor angle is too small, the car will feel
very unstable at high speeds and will react very
nervously on any steering action. If the castor angle
is too big, the tyres will wear very quickly and you
will lose grip in corners. The reason for this is that
castor (on the front wheels) will produce camber as
soon as you turn the wheels. Finding the right balance
is key again.

I can hear you thinking now: ‘The workshop I’m
visiting has a very expensive test setup to do these
alignments. How could I possibly do that on my
garage floor?’ The good news is - you can! The bad
news is… it’ll take you some time to get there. If
you are serious about this, you could bring your car
to this workshop to try a new setting you’ve figured
out, but in the end, it would cost quite some money.
An optimal setup for a nice, warm, dry track is different
to that for the cold, wet roads at home, so
you might end up queuing at the workshop every
week.

So it’s time to make a decision here. Are you going
to try a handful of general setups during a season?
You might opt for the workshop.
If you would like to end up making your own setup
per different track or according to weather, you
could start investing in your own equipment. You
could look at companies like
www.longacreracing.com who are selling quite
interesting low-budget solutions for Geometry
modifications. If you search on the Internet, you
will also find other companies, and also descriptions
of doing a setup yourself using small ropes.

There’s one thing which is important to understand
before you start. The floor you are doing the
setup on needs to be level and you must put some
weight in the driver’s seat (preferably something
that matches your own).

One more thing: say you’ve added a shim in the
front suspension. You’ve lifted the car, removed the
wheel, done the shimming and built it all together
again. After doing that you should check what
you’ve done, but you shouldn’t just measure again
after lowering the car! Roll it forward and roll it
back again! The suspension needs to settle, and
you do that while rolling the car back and forth.

Your car came out of the factory with what you’d
call a general setup. Depending on what you want
to achieve, there are a couple of different setups
that you can use as a starting point to find your
own. Lotus has released quite a few setups for the
Elise, Exige and 340R. You can choose one of these
as a starting point and start modifying from there.
If you’re doing your own Geo for the first time, I’d
advise you to take it step by step: e.g. first do the
Toe-in / Toe-out until you’re satisfied with the
behaviour. Next step could be the camber, etc.

It’s winter - a good time to start understanding all
of this and preparing yourself for a new season.
Once you’re able to do your own Geo, I’ll start nagging
you about bump steer settings and springs
and dampers.
