Editing Brake discs (section)

===S2 Elise and Exige===
Series 2 Elises are fitted with 288mm vented iron discs.  308mm 4 piston AP Racing brakes were on option on the Exige S240 and S260.

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.
