What Clutch?

You want a "firm" pedal stick with a Borg & Beck 3 finger style. This will require the overcenter spring to remain hooked up and will require effort. Otherwise go to a Centerforce and remove the spring. There are weights on the fingers which apply more clamping force as RPM increases. I used one in my Challenger with a Hays disc and had no issues behind the 420+ hp 440 Six Pack
