Nope, with hydraulics they're an easy pedal... Even with linkage they're good on the street! McCleod also offers (drag racing stuff) a button, valve, and solenoid that let's you "set" the clutch in the same manner as you set the brakes and hit the line lock button, then hold the button in, let it go on the yellow!!!! Huge changes in clutches and discs with all new materials.... The double disc pedal pressure is about the same as the old 10.5" Mustang clutch now!!!!

Now, the Soft Lok I use for racing, well that one will build you up a good left leg!!!!!!!!!!!!
