Frankly this is all crazy. ANYONE using a sintered metallic clutch disc for the street will be replacing it within a few months, max 25 k miles even with a pretty strong driver mod. Note the web site says 'RACE' For good reason In road racing the clutch is an on/off switch. DD not so much. The part about a "unique" modified pressure plate is just shimming the diaphragm to increase clamping pressure so that the formula for calculating torque capacity can be adjusted for claims of " omigod kazillion foot pounds torque capacity" .NOT actual dyno torque capacity test results.
good OEM sachs clutch. driver mod. Enjoy for miles and miles of smiles
My take. So many clutch threads throughout social media. Driver mod required is pretty obvious
