My clutch is fine, but my TOB is squeaking pretty bad, and I figure if I'm going to go through the trouble of pulling the trans off, I may as well do the clutch while I'm in there. So here's my question.

I just finished reading on Maximum Motorsports' website that Ford used a non-conventional clutch disk thickness on their 11 inch clutches, which can present a problem when replacing the clutch. They recommended converting to a 10.5 inch disk for several reasons.

The only thing MM has on their website are McLeod 10.5 inch conversions, and I don't really feeling like spending that much on a clutch.

If I bought the Ford Racing 10.5 inch billet steel flywheel:

and a king cobra clutch, would everything bolt up alright? I work with someone who tried to replace his stock clutch with a 11 inch Centerforce and Hays aluminum flywheel, and the stack height wouldn't work for him on his 03 GT. I know he couldn't get the clutch to engage/disengage properly for weeks. He ended up going with another stock setup after all that money, and I just don't want that to happen to me.

Thanks!!!

just buy a Centerforce DFX 11 inch and you'll be fine.. I swapped to a 10.5 inch with Fidanza aluminum flywheel on my 04 with my last clutch and now Im back to a billet steel centerforce flywheel and DFX. I like it ALOT more now...pedal pressure is like stock and the clutch is rated for some pretty good TQ.

If you want, you can pull the flywheel, take it to a machine shop and have them drill/tap new bolt holes for the 10.5" clutch, and they can drill holes for the alignment pins as well. While you are at it they could do a resurface as well, and that's all you need.

I wouldn't adivise that.. drilling into a weak stamped steel stock flywheel that has been heat cycled countless times is a recipe for disaster. get an aftermarket flywheel and do it right.

I'm a low buck guy, I went with the Cobra clutch and while you're there, pony up for an aluminum flywheel. It's not like you tear into it every day, and it's a good mod. IMO money well spent.
