which clutch disc to use?

I'm looking for some input on which disc to use? I'm putting my 500+ HP engine back after winters upgrades. I had a Sachs organic disc, which I installed new with a KEP stage 1 last year. I have a Sachs segmented disc, which I'm trying to decide whether to install. Any one with any comments/experience on the segmented disc. Mostly country driving, at WOT.

This segmented disc is also thicker, spec at 9.65mm as the organic disc is 9.45mm. Will this affect pedal press. any? I see some of the Sachs discs spec out at 8-10 mm. Philip

Hello, the disc pictured is a Centerforce unit. Base Sachs parts but with upgraded features. These are set up and sold only with the matching pressure plate covers. The dual friction tech is full face lining on one side w segmented carbon kevlar on the other. There are updates to the pressure plate too which increase clampload. Great for street but also great for track use.

The bullet proof top dog clutch for the 930s are the Centerforce DF255255 (low profile cover)

I would recommend using a stock disc with the KEP pp (also great clutch but stiffer pedal). Yes it is important to have proper disc thickness!!

Yea, I ended up putting the organic stock disc back in. I felt kinda guilty breaking up the clutch and PP. Maybe next time I'll use the Center-force setup. Thanks Philip
