anyone driven one? how does it compare to other stock clutches? what about aftermarket stuff? Katech sells this kit with a custom flywheel so it'll work with everything else since the LS9 has an extra flywheel bolt. its 8lbs lighter than a LS7 clutch/flywheel package and 800tq holding with "stock engagement"
