New clutch for racing - 96 Cobra

There's not much left in my current clutch and it's getting unbearable to drive. It takes about 100 lbs of force to push the damn pedal in when it's been sitting. I've tried adjusting it to no avail. It's slipping on the track and whenever I get on it hard.

So, I was planning to go with a lightweight Quarter Master clutch/flywheel. The catch is that I'm not quite ready to take my Cobra off street duty yet. I still drive it daily.

Finally, my question: Is there a good race clutch for my Cobra (stock T-45) that I can drive on the street occasionally or should I hold off until I am ready to dedicate this thing to 100% race duty?

Jimmy,

I just installed a Spec Stage 2 clutch, along with their aluminum flywheel in spring 2003. My car still has the original T45 installed, along with some minor engine and a ton of suspension mods. In the year plus that I have had it in, I have found the clutch to be quite streetable. The pedal effort is not really any harder than the stock unit and it sure grabs a lot better. If I have had any issues on the street, I think it's mainly from the aluminum flywheel, but once you get used to it, it's not really a problem. My wife has driven the car a number of times, and I think that she has killed the car due to the clutch twice now in two years. I put that down to the difference between the Spec clutch and the stock clutch in her SVT Contour. The Spec clutch handled autocrosses and open track days last year with no difficulties.

I bought mine from On-Track Performance (http://www.recaro-seats.com/)

Are you sure you need a new clutch? When I had my 87 GT I had an issue with clutch cables "melting". I had headers on the car...and the clutch cable was just close enough (was not touching) to start to melt. It would be nearly impossible to press the clutch down until everthing was hot. After that...it required normal pedal pressure (for a Centerforce).

Just a thought.................

Just get a QuarterMaster. They make the best stuff. Wouldn't the 8.5 inch setup they offer work on the street for you?


Or, it may be time just to pull the car off the street!!

Thanks for the input guys.

I know the one I have is bad. I can't accelerate out of a turn in 2nd gear without the clutch slipping. My last event at CMP (WOW-that was a long time ago) I had to do the last two sessions in 3rd gear. I haven't figured out why it seems so "heavy" but I know I need a new one.
I plan to talk to the techs at QuarterMaster and see if their race unit would be streetable for a short time. I guess the 8.5" unit is the only one they offer for the 4.6/T45?

I've had a Spec stage 3 and AL flywheel in mine for a year and a half with no problems. After a few break in miles it is perfectly streetable. Occasionally chatters a little in reverse, but not bad. Pedal effort is very light

If you call up there, see if there is a Jeff Neil there. He is the super cool guy that hooked me up with there stuff a couple of years ago. He can help you out for sure.

As far as the 8.5, I THINK it is designed to be used on the street, but I am not sure. Jason, Bryan, and I put one on once a while back, so maybe they will chime in about streetability. I would think QM offers more than just that one, but if they do, they would be a lot smaller and then you start getting in drivability issues. Just ask Shugg how tricky it is to get a car rolling with a small clutch!

I tell your mom 'hi' for you!




PS - Just for clarification........... I work with his mom at the bank. Did for about 3 years before I put it all together.

Here's another vote for the Quartermaster clutch. I've raced two years now around 20 races on this clutch after testing it a long time ago. It's the Extreme V 8.5 Sintered iron sprung hub version. I used to go through two clutches a year till I put this one on. You can slip it when you need to without worrying about frying it. The aluminum flywheel and entire clutch assembly only weigh 18lb's. It is also rebuildable which saves money on the long run.

Thanks again, guys. Still looking for feedback from Shugg.

Thanks for 'splainin the comment about my mom. I'm sure the gang here would be all over that.

I tried calling QM today and got nothing but VM. The web form for tech inquiries wasn't working. I'll try again tomorrow.

I'll try to get Jeff Neil and mention the "Extreme V 8.5 Sintered iron sprung hub version".

We use the 7.25" triple disk Quartermaster and I can definitely state that it is NOT streetable.

If you don't have any luck trying to get Jeff, let me know and I'll try to get someone to work with you.

Wilson, are you guys having any problems with the clutch like getting started, or loading? The Extreme V 8.5 comes with options of the disk material. The one I tested was the Sintered iron with the pucks on the disk. I haven't had any problems getting around the pits, or loading at all. What does the 7.5 weigh? Are you using a flywheel?
And lastly did you guys see my car in the Quartermaster catalog?
