I bought a ram 10lb billet steel flywheel and centerforce dual friction clutch for the formula. It's all for a newer 1pc rear main. When I checked the clutch to flywheel clearance, the cluth hits the bolts that hold the flywheel on. I called ram and nobody was home, summit didn't know anything and centerforce wouldn't answer. I guess my question is has anybody else used this combo? Do I need to use a ram clutch? A puck style clutch with no springs? Any help is appreciated. Thanks, Ryan

 

Is the sprung hub forward towards the engine or back towards the pressure plate?

What flywheel to crank bolts are you using?

Pics might help.

 

I was using the arp flexplate bolts called for, and the clutch disc is facing the correct direction, there was just a tiny gap between the disc and flywheel.I finally got ahold of ram today, and they said you can't use a clutch with a sprung hub, it has to be a solid hub. Summit and jegs didn't have this in any notes on their website or their books if you call them, and there was nothing on rams website. I guess ram dropped the ball on that, it would be helpful to know before the car is torn apart. Oh well, wait on parts now.
