OEM Clutch vs Stillen

[GTMikey]

I know there is a thread out there on this but some of it is dated.

I have a Heritage with a Hefner Pulley and Tune. I ran about 10 1/4 miles on a drag strip and 2 days of open track and the clutch is ready for a change at 6500 miles. I drive it fairly aggressive when I do drive and give its only 100hp over stock I was wondering about the varying opinions of another OEM clutch vs Stillen. Thanks for your input.

I have driven both stock clutch and Stillen. The Stillen to me, was a little less forgiving (a bit more precise). Some folks like that better. It took me a short while to get used to.
My current GT has the stock clutch - I drive conservatively, and have a Whipple putting down 730+rWHP, with > 10,000 miles.
I think with a pulley and tune, you are fine with either. If you are going to up the HP at some time, might as well put in the Stillen.

I have used both in a couple applications and my preference would be the Stillen for the quicker engagement. It still drives very much like stock in terms of pedal effort, but it doesn't have the super long travel that the GT OEM clutch has. If you drag race your car, I don't doubt that that was the cause of you toasting your clutch. If you ride out the GT clutch even the tiniest bit, it doesn't seem to like it, and with the stock setup you're way more likely to do that. You really have to get off the OEM clutch quickly or you'll have the metallic scent of roasting clutch trailing behind you for awhile. It usually comes back to life, but eventually you will toast it.

Stillen seems pretty robust as well despite the fact that it's not specifically a "high hp" design application. I think I'm still on the first one in the TT setup, and the car has seen many track days and much use on the street. It won't last an eternity under super heavy use, but I prefer the way it feels while driving versus some of the heavy duty clutches I've had in the past that will give you Arnold Schwarzenegger's 1976 left quads and hamstrings.

Come on, you can do your leg exercises while driving.

I don't have any experience with the SPEC clutches, so I will refer you to Kendall at Cooltech as that is where I will eventually go.

I have had Stillen install their clutch in my car twice. The first one lasted only 2000 miles....and I did NOT drag race, dump the clutch, or do anything aggressive for the clutch to perform so poorly. I don't drag the clutch or stay on it. I did not start out in third gear.

I will NOT be going to them for any kind of work in the future due to the state they returned my car to me - Several bolts only hand tightened. Several bolts missing. Several rivnuts stripped. Scratches in the paint on both quarters of the back deck. I don't see how they could have checked their work before signing off on returning it to me as they should have immediately noticed that there was an exhaust leak due to only hand tightening the bolts.

The first go 'round, I showed up at their facility to find they used standard 'masking tape' as a means to 'protect' surfaces.......this practice could have, though didn't do any damage.

I don't see them taking their Ford GT service seriously as they appear to be mainly an import oriented company.

Kyle Millen is a very nice fellow, though when the rubber meets the road, it is the Service Shop that performs the actual work. Hopefully other's have had good experiences.

We have discussed your experience and it saddened me that you had such an experience.

Now IMO the AP clutch as offered by Stillen is a quality piece however to the rest of your experience I can only say that I know that you were/are not happy.

I'm very happy with the Stillen clutch. Somewhere around 60k and counting.

Still works like new.

My Spec clutch has 6000 hard miles on it and at least that many left. I like it.

I have a Spec clutch as well and it seems to be bulletproof, even with 1000+ HP. That said, it feels quite a bit different than the stock clutch, stiffer and with quicker engagement. A bit grabby when new but it does smooth out with some miles. The Stillen clutch feels more like stock but I doubt it will last as long as the Spec clutch. I have had a bad experience with Stillen as well as helping another member who had a tough time there.

I prefer the Stillen clutch. I have never had my GT worked on there but I like their products. I have had a bad experience with service at Whipple but I don't talk about it.
