kmillen,
I am interested in a clutch but want to know if all the R&D is done? Have you installed one and driven it yet? Can you compare your product to the one that Spec has developed for Joe's TT application?
Thanks!


All of the R&D is 100% complete. I have them sitting on my shelves ready to go right now.

We have not yet driven with one in the car. We will be installing that in the next couple of days. The transaxle is out of the car and as I type this they are installing the new 3.9 diff ratio. When we re-install the transaxle we will also be installing the new clutch as well.

Before comparing our product to the Spec clutch I have to let you know that my information regarding the Spec clutch is not complete. If anyone has a link or a place that I can study the Spec clutch I can make a more accurate comparison.

From what I understand the Spec clutch is more of a re-line of the friction material more so than a complete replacement clutch? With our clutch we are making quite a few changes.

1) We changed the center plate design from a 4 spring to a 6 spring. The clutches have been designed with an alternative 6 spring Driven plates with increased torque capacity compared to the original four spring Ford GT driven plate. These driven plates have been used extensively by A.P.Racing for performance cars such as Ferrari's.

2) The standard (and I assume Spec) clutch has a release point after 90MM of travel or 3.54 inches. The new cushion segments will release after 65 MM or 2.55 inches.

Also we use a different friction material. This material has a higher thermal performance and fade resistance than the original F510 material.

One of the major benefits of our clutch is that it is made by AP Racing. The same company that makes the factory clutch and was involved in the original development of the car.

I am definitely in for one when the stock unit goes and it will probably go fairly quick now after the Whipple install.
Question for Kyle,
I don't like the engagement point of the stock clutch which is very high in its travel, will the AP clutch engage lower in the arc?

I completely agree with you and that was something that we addressed when developing the new clutch. Please see the above post for the complete description on how we made that change.

Kyle,
When will you be at C&C again? I'd like to get a feel of the clutch. FYI, it may rain this Saturday so it may not be a good day to go.

Steve, I thought you discovered a way of getting factory replacement clutches at no charge, by just bringing your GT to your local Ford dealer. Didn't the last time you went to the dealer your car was returned with a new clutch, free of charge?

:lol:rofl:lol

I can go to C&C anytime. The car is still apart as of right now (it's getting the first 3.9 diff. ratio installed.) So I probably won't be able to make it down there this Saturday. Maybe we can plan to meet up next weekend? Or if you'd like you can always stop by our shop.

Thanks, I'm interested to hear how it works when you drive the car.

Thanks for the concern Page. ChrisA had his car at the same dealer at the same time and wasn't very pleased with the service or TLC his car received either (to put it kindly).:frown:thumbsdow

You guys need to load a valet tune before bringing the car in for service. I made one by mistake, but it can be useful at times. The tune had the superchargers bypass on always (no boost) and limited the RPM to 3000. For a Valet tune I would at a speed limiter of 30 mph. That should keep the car out of trouble.

To be really safe, one could have zero boost, 2000 RPMs max, and a top speed of 15 mph. That should allow them to move the car around the dealership service bays, but not much more than that!

:lol
