We replaced the stock clutch with this STM slipper clutch ($1050) from Lockhart Phillips, which uses the stock plates and one large diaphragm spring. A ball-and-ramp mechanism deep inside controls slippage under deceleration. It's a must-have for classes that permit it, as it almost eliminates wheel hop on downshifts and makes for blazing corner entries.
