Mcleod RXT clutch on 2011 Mustang GT, stock flywheel

Friction is independent of surface area with non-deformable surfaces.

So the fact that it has less contact with the friction disk doesnt mean anything as far as how much power it will hold. The coefficient of friction of the clutch material and the clamping force created by the pressure plate is what matters.

Less surface area will correspond to less life though.

Awesome info, I wouldn't have thought it would work like that. Makes sense. Thanks for bringing some science!

Watch out as you put miles on the car. I tried using an exedy flywheel with my rst. The exedy has more surface area compared to a stock flywheel (4.6 car) but the disc still hung over by about a quarter of an inch. After about 1000 miles the car would creep when the clutch was depressed. When we pulled the tranny there was a quarter inch ridge on the disc where it wasn't touching on the flywheel. I've been fighting a problem with the rst since may finally got anew clutch and flywheel from McLeod. I've had my tranny out 3 times and dumped $3k in parts and labor on the rst so watch it carefully.
