Action Clutch Stage 4 Kit w/Flywheel 12-15 Si
NO CLUTCHES WORK WITH THE STOCK 12+ SI FLYWHEEL, WHICH IS WHY YOU NEED A KIT WHICH COMES WITH A FLYWHEEL LIKE THIS ONE.
This kit should hold around 170% more torque than the stock clutch is capable of. This is a great kit for supercharged builds and turbo builds. We personally have turbo customers using this clutch at 100wtq over Action's ratings - daily driven and at the strip.
