The only reason I mentioned Spec is because they're one of the few manufacturers that I can recall who's stuff is manufactured for higher clamp loads with matched components. It's not modified stock stuff, pieced together with other brands of components. Not saying there's anything wrong with Patrick MS's setup. Just pointing out that there's complete matched kits that accomplish the same thing for probably less $?
And I wholeheartedly agree that without question, the place to save weight on a G50 is the pressure plate, not the flywheel. I think the factory 3.2 G50 pressure plate is made out of lead?

It's
extremely heavy!
Back on topic..... Good thing about 915 trans. is the wider selection of clutch components. G50 doesn't have nearly the variety.
