Recommended for single mass flywheel (SMF) when original design is DMF to achieve optimal performance. This kit uses the same Race Engineered SFI approved pressure plate as stage 3 daily package. The disc is designed for the special needs of a vehicle with circuit racing in mind. Kevlar friction material is used for its unique static to dynamic ratios of friction co-efficients at high energy levels. This translates to a perfect transition from one gear to the next. Discs are assembled with only performance components and equipped with torsion springs functioning as a damper between engine and gearbox.
