Anyone have a Kevlar clutch disc?, If so, what's your experience...good/bad??? Options

I have a V-8 car with 500 HP and the stock 930 OEM Sachs disc is starting to slip. I have the KEP Stage 1 930 pressure plate and was told that it would hold 550lbs of torque (with a stock disc). My engine puts out 470 ft. lbs of torque...so this set up should work according to KEP. However, it has only 9-10K miles on the stock disc and it's starting to go already. (Maybe that's about right...considering the amount of performance I have and my driving style?)

I am considering going to Clutchnet's Kevlar disc. Renegade swears by this type of disc for their high HP V-8 applications. I remember Scott telling me about how wonderful and streetable they are. Nice smooth OEM engagement and much higher torque holding capabilities...and long lasting durability to boot. He said that the Kevlar discs need to be broken in gently for approximately 500 miles.

Anyone out there have a Kevlar disc in their car?...If so, how has it worked for you???

Thanks for the feedback!

The disk is also only "wafered" on the pressure plate side. The advantage of that is the disk does not have to slide on the input spline every time the clutch is used. Basically it releases quicker but still allows smooth engagement with one sided wafered.

Are you talking about the marcel (think wave washer) that is sandwiched in the middle of the stock OEM Sachs disc? Or are you talking about the grooves that separate the pucks or disc material?

I think you are talking about the former. Maybe I should have Kennedy replace my OEM material with a more aggressive (higher coefficient of friction) material and have a continuous lining all the way around like the stock disc. Sounds like that is what you have done. I'm trying to imagine half a marcel on the pressure plate side only. Did you have Kennedy use your stock disc core to build up what you currently have?

Thanks for the input guys.
