Stage 3.5 Full Face Sprung DXD Clutch kit and Southbend billet steel flywheel, used for ~8k miles, only taking it off because I'm parting out the car. The car was never launched with this kit installed, not even once.
This is THE BEST clutch for boosted applications, quick engagement but easy to drive daily, no "on/off" nonsense like the os giken clutches and is rated for over 650tq. The flywheel is about 8lbs lighter than stock and has little to no chatter like typical lightened flywheels.
$375 Shipped for the clutch
$375 Shipped for flywheel
$700 Shipped for both
