more clamping force

if you have a clutch that can withstand more torque being transfered through it, then thats only going to be able to be used with a cover plate that can clamp it more effectivly

not so much of a problem with a hydrulic clutch, but with t cable opperated system you'll need bigger legs to operate it (or use a longer pivot/moment/some physiscs thing i can't rememebr like fulcrum or somethng)
