The EXEDY Stage 2 Cerametallic clutch kit with 4 pad disc for 2004-2020 Subaru STi is available with either a "Thin" or "Thick" disc. The thin disc offers quick shifting, but recommended for circuit racing only. The thick disc has a good heat capacity and performs well on the track. Not recommended for daily driving.
Vehicle Fitment:
• 2004-2020 Subaru STi
* These clutch discs are very grabby! *
* Not recommended for daily driving *
What's the difference between the Thin and Thick Discs?
The Thick Disc has a great heat capacity and therefore better durability in demanding applications and typically have less inertia than a stock disc. Works well for rally and track use and can be street driven, but will be very grabby.
The Thin Disc offers greatly reduced inertia for quicker shifting, and improved synchro durability. These discs are approximately half the thickness of a stock disc and are recommended for circuit track use only.
What's the difference between the 3-Pad and 4-Pad Discs?
The Stage 2 Cerametallic Clutch kits come with either the 3-pad or 4-pad disc, also called "pucks". The 3-pad is a little lighter, while the 4 pad will have more surface area. They both have the same respective clamping force and torque capacity. Both are sprung discs. The 3-pad disc will have a harsher engagement and is known to "shudder." They both will be hard to slip as they are very on/off when it comes to engagement. They are very "grab and go!" If you need a good daily driver, the Stage 1 organic clutch is a good choice!
Cushion Button Disc:
The remarkable Cushion Button Disc combines cerametallic button facing with marcel cushion springs to maintain comfortable driving while supporting a respectable amount of power. Its smooth engagement is ideal for the street, and thanks to its heavy duty sprung hub dampening assembly, can handle the power of high torque motors.
Clutch Cover:
These clutch covers are designed to achieve a clamping load that is approx. 40% higher than the OEM part allowing a higher torque transmitting capacity. Ductile material is used for all pressure plates and, high burst strength can be achieved in all temperature ranges.
Includes:
• Pressure Plate
• Clutch Disc
• Throw Out Bearing
• Pilot Bearing
