How much stiffer aftermarket clutch vs stock
 

I had a new clutch and lightened flywheel installed on my AAM tt build. I'm reasonably certain that a clutch designed to work with 500hp would be harder to disengage however I just wonder how much. I wish I had a way to measure foot pressure needed to push clutch pedal, feels to me really friggen tough. I'm going to guess at least 5 times more effort than stock. Comp segmented clutch, Z1 hd throwout.

I just put in a stage 2 and i would say it's about 2x harder then stock

You're left calf is gonna be bigger than the other :ugh2:

Thats for sure, stop and go traffic and I start getting calf cramps. Which slave cylinder controls that part of the mechanism, one at the firewall or throwout? Be nice to find a substitute slave that helps. I'll deal with it either way just wondering if this was basically to be expected. I did read here to check master cylinder to make sure not overfilled, it was and I said YES! Sadly didn't help.

You could get a RJM clutch pedal. That will give you a little adjustment and change the leverage point. It helps!

Excellent point, I do have the rjm older version..I'll check it out and go through the adjustment procedure again, thanks!

I have the RJM v2 (older) as well. Made a huge difference over stock pedal using the Clutchmasters 725 twin-plate. Once we got all the bugs out, it feels almost like stock; butter-smooth.

Thats great, know what I'll be doing tomorrow!

Problem solved, backed off rjm knob to zero and gave it 2 turns, was set at about 7. Muuuch better, thanks ZOM and lj909 (and to Ryan for producing this wonderful piece)!!
