I'm using a Center Force Dual Friction
B.T.W. Did you know that the "Dual-Friction" (and if I remember correctly this was initially a C.F. introduced product, and what elevated them as a "top-Rung" player in the market place) type clutch disks, that in the 'original' configuration, had the "organic" composite facing the flywheel and the more exotic material (Kevlar most commonly) facing the pressure-plate? This intention was due to fact that the pressure-plate ring is generally a smaller mass than that of the flywheel but realizes the same forces and hence generally reaches higher operating temperatures and that it was the higher temperature tolerance of the not organic material, which becomes "greasy" as the bonding resins begin to cook, that led to the development of the Dual-Friction product.
But, . . . . . then, the manufacturers realized that the "ductile-iron" pressure-plate rings available on the market as being utilized hadn't been developed for these 'exotic' friction materials and proved that they weren't compatible, particularly from the metal displacement standpoint; so then someone looking for a "quick-fix", got the bright idea of just flipping the friction materials positions (nobody will notice!) and then declaring that you just needed to 'also' buy one their "steel" (friction faced) flywheels for compatibility!

But baby, this has made a lot of money for those in the industry!
