Contour Enthusiasts Group Archives Forums Modifications Duratec Performance Clutch question

I know the grizzly and Ram clutches use stock Luk / Ford pressure plates. If they are changing disc materials without changing clamp force, can't you end up with mis-matched components?

I've always wondered - my grizzly clutch is pure kevlar pucks with a stock pp. Since kevlar has a lower coeffient of friction (by quite a bit) than standard clutch linings - did I trade off longer life/better heat resistance for less holding power? Or are the limits of clamping force already well above where these engines are going to be at?

{Even though my clutch is still good, I think just for peace of mind (especially with all the failures recently!) if I did it again, this is one spot where I'd stick with SVT spec oem equiptment from a Ford dealer. Sure you may pay a few hundred more - but if it aint right you know it'll still be a warranty fix from Ford.}
