Lotus OEM Fitment
S1 Elise
MMC
The earliest Elises were fitted with a very lightweight Metal Matrix discs, these discs had an extremely long life expectancy with a very low weight.
The down side of the discs was their fragility at high temprature and poor ability to shed water when driving in rain, often providing interesting moments for the driver if used in anger on a rainy day.
These discs were discontinued due to cost when problems were incurred with the original supplier.
Standard cast iron
These discs followed the MMC disc as the standard brake disc for the S1 Elise.

Lotus Part Number:A111J0141F
S2 Elise
288mm Vented Discs
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 callipers.
