when grabbing your cable at the firewall adjuster you should be able to pull on it and get about a 1/8th to 1/4" movement away from the firewall.

if you have a double or triple hook quadrant do you have it hooked in the correct spot?

to tight is not good at all and is hard on the thrust bearing on your crankshaft....

I'm not surprised why did you get a spec clutch in the first place?
My transmission shop properly adjusted my spec stage 2 clutch using a UPR quadrant and firewall adjuster with a stock OEM Ford
clutch cable and my spec clutch still failed at 5K miles.I think
that my spec clutches are inferior junk and alot of people seem
to think so,unlike the biased people here at AFM how have a
spec clutch and defend spec just because they have a spec
clutch on their Ford Mustang.
Uninstall your adjustable clutch cable and install a new stock OEM Ford clutch cable that may fix your problem.

I ran the setup you described: Steeda adjustible quadrant, firewall adjuster and Spec 2+ kit for about 50k miles with ~400 whp and no issues.

When I installed mine, I adjusted the part where it goes to the clutch fork as tight as I could get it and then used the quadrant slot closest to the firewall (mine had 2 slots) and adjusted the slack out at the firewall and it may have been 1/2" adjusted out.

The pedal had about 1/4 to 1/8" slack with the cable when I was done.

The guy I sold my car to has been running it for ~7,000 miles + also with no issues.

The only thing to mention was the Spec t/o bearing failed shortly after install in my case (it squealed), but a new t/o bearing fixed that. =)

I must be lucky, because I had the Steeda set up the OP has for 75,000+ miles on my car with 0 issues and the Spec clutch for well over 50k miles with 10# of boost.

The only issue with the Spec 2+ kit was the t/o bearing and that was due to a clutch fulcrum bolt issue that caused it to fail.


To the OP:

The original OEM Ford clutch quadrant is plastic and they commonly fail, the Steeda piece is good quality and from my experince with it, it is a good piece. It took the abuse of many clutch side steps and the Spec 2+ clutch also survived many boosted "no lift" on gas shifts without slipping.

Get it adjusted correctly and you should be happy with both parts.
