recommended clutch?

running a 400bhp plus 930, all the tweaks under the cis system and she's on a standard clutch. I'm feeling her slip slightly and don't want it explode under pressure re bell housing etc.....should I put a harder clutch in and what type......all pointers please very welcome.

Go with the stock rubber centered disc. That way you'll know positively and instantly when it fails...no warnings, no questions asked

I can't give you any cross-comparison perspectives, but I can give you personal perceptions and experience. I love my KEP Stage 1 PP/Sachs spring centered combo. Much lighter in weight (IIRC, 14 lbs. less). Went that direction when my stock PP/Sachs spring centered disc started slipping slightly after I did all the mods to my car. The age of the clutch and the extra HP began to show. Personally, you probably don't need to go beyond the Stage 1 with the HP you're running, unless you want to put up with a pretty stiff clutch. Some people don't like the stiffness of even the Stage 1, but I never found it all that terribly different than my stock and quickly got used to it. Hey, it's a mechanical linkage after all and will never be as easy as a hydraulic.

Did some searches on the board when I rebuilt my engine last winter.
Ended up buying KEP stage1 kit.
Clutch is a little stiff, but not very much more that stock. Happy with my choice
