Clutch Size Questions?

[Carlwalski]

What would be the driving difference between say, a 10.5" and a 11" clutch?
What benefits would an 11" clutch have over a smaller 10.5" or 10" clutch?

More bite? Less pedal travel? Quicker release? More pop? 



I have no idea, that's why I'm asking.

the larger the diameter the better the grip not only does the increase in surface area increase the hold but the the hold increases more due to the diameter of the clutch so the larger the radius the more advantage it has

What he said. that 1/2" of diameter is a 15% larger surface area on terms of friction. The grabbiness is a combination of pedal motion, springs in the hub, material and temp of the friction material, surface of the flywheel, and pressure plate design.

Thanks guys, so I should look at upgrading the Keisler kit to an 11" clutch? 
I really need to start learning how and what a clutch and manual transmissions does.......

Not necessarily. Like tires, a lot of advances have been made in clutches in the past 30 years that will allow better holding power and a lighter feel. Centerforce is one that immediatly comes to mind, but most manufactuers have a variety of linings now days.  There also are smallish 4 and 6 inch competition units as well as multiple discs that provide HUGE increases in holding power for things in the 700+ range.
