Going lower than 110 on the front will cause the wheels to catch on the clam under heavy braking and cause early lock-up. Going stiffer on the springs (say 450/550) will allow less damping, but, they will be far less forgiving when you make a mistake. the Do a SELOC search on +spring +rates

	Dropping the ride height needs the stering rack riser plates replaced with the 10 notch motorsport version to reduce bump steer.		Dropping the ride height needs the stering rack riser plates replaced with the 10 notch motorsport version to reduce bump steer.

	Whilst you could run 195 tyres on the standard 5.5J front rims, to allow the sidewalls to do their job properly, it is highly recommended to upgrade the front rims to 6.5J or 7J which unfortunately needs a whole new set of 4 like TeamDynamics 1.2 £500 or Lotus Motorsport OZ or Exige Spider £1,000 See [[S2 Wheel Options]] for more information (Rover and Toyota engine cars have different rear offsets).

	'''PS If you are not able to consistently exceed your current road tyres capability on track and regularly catch oversteer with a dab of oppylock, "upgrading" to cut slicks too early will probably hinder your development as there is less feel/feedback and the breakaway is sharper (less progressive).''' Honestly its a LOT easier to learn on ~~List 1A~~ road tyres.

	You don’t have to have solid/uniball rear toe links to run cut slicks - Lotus shipped the S2 135R and Exige on A048s with standard toe links, and there are many thousands of track miles done each year on these with an extremely low failure rate (the major problem was the S1 design) ... BUT the more hours you spend using the capabilities of cut slicks pushing the car hard on track up the curbs etc the higher your exposure to risk, so at some point when you have a spare £250 its worth doing on an S2.
