Personally....since that's being bandied about.....I'm a believer in KISS.
I can see no advantage in changing the 914 clutch set up untill you NEED a very stiff pressure plate to hold the HP...one that overpowers the stock cable set up.
IIRC, Kennedy will redrill a stock 914 flywheel & provide a suitable 215mm pressure plate/disk to hold the torque of a moderately modified 3.0L or 3.2L. The weak point is the 901 tranny, not the clutch....personally, I'm opinionated.
Currently, I'm running a 215mm stage I Kennedy set up behind my hotrod 2.7L. The clutch has had no problems hazing 225 Hoosier stickeybuns during 2 AX seasons......prolly 350 passes.
The cable has been in there for at least 7 years, same with the pivot wheel, clutch tube is sound (never repaired)....yada.
The tranny was rebuilt by a VERY good tranny guru, but it's starting to weep frrom the front seal.
If you're gonna put more stress on your car than that, I can't help you.
