mhuffman77 Posted December 19, 2012 Report Share Posted December 19, 2012 Hey everybody! I am new to this forum and to GT500 ownership and would like to get any personal opinions on clutch kit manfacturers. I have a 2008 GT500 at a little over 600HP to the wheels. I purchased this car a couple months back with no clutch slippage and just a minor notch into second and third before the tranny got moving and heated up. After a couple months of the ocassional stop and go traffic and colder weather it seemed more apparent that something was wrong. Then a couple of weeks ago the clutch started slipping and it has been a very steady decline in performance since. I need a clutch that can handle stop and go traffic. I am not looking to take it to the track but my main concern is that I get a clutch that will take anything I can throw at it. I do not want something that will require replacement in another 10k miles. Any help would be appreciated. I have been reading through all the older topics on here and just can't seem to make up my mind. The only thing I know for sure is I've gotta get this thing replaced really soon. Not sure how much longer it will even be driveable at this point. I am kind of leaning toward the Spec Super Twin Disc kit. Any owners of this clutch? Again Thanks for any input, it is much appreciated Link to comment Share on other sites More sharing options...
springer Posted December 20, 2012 Report Share Posted December 20, 2012 I had the SPEC and removed it, and went with the Ram twin disc and haven't looked back. Link to comment Share on other sites More sharing options...

que4dog Posted December 20, 2012 Report Share Posted December 20, 2012 I don't see many post about the Spec 3+ single disk but if you do not track the car or do long burnouts it is a great choice. It feels better than stock and will handle your HP easily and save you a couple hundred dollars. You would have to purchase a new flywheel to use the single disk but your total would still be in the $800 range or less. If you take the car to the track, I would urge you to get a twin disk.

0201212 Posted December 20, 2012 Report Share Posted December 20, 2012 I have the act twin disc and love it. Great pedal feel and very consistent. Link to comment Share on other sites More sharing options...
springer Posted December 20, 2012 Report Share Posted December 20, 2012 Twin disc or single? SPEC was a single disc, 3+. Total junk in my opinion. And Jeremy, their customer service rep is the worst. Link to comment Share on other sites More sharing options...
07gt500conv Posted December 20, 2012 Report Share Posted December 20, 2012 I put in a McCleod RXt and love it. Link to comment Share on other sites More sharing options...
mhuffman77 Posted December 20, 2012 Author Report Share Posted December 20, 2012 Hey thanks for the feed back. The Spec I was looking into was actually the twin disc though. Here is a link: http://www.mmautoperformance.com/spesfg5sst-ford-shelby-gt500-05-10.html?gclid=CKTZv9DoprQCFQ3nnAodWBIACQ I found a shop in Suwanee GA, Zen Motors that can order the kit for the same price $1,259.00 and the install fee is $495.00 which includes replacing transmission fluid. I should be able to get total repair done for under 2 grand including good tranny fluid. I was thinking Amsoil or Royal Purple. I know the single disc would work but I would rather maintain the twin disc setup that is rated well over my power output. Its crazy how bad my clutch is now, smoke everywhere if you get on it. Looks like I'll be keeping it uder 2k revs till I get the new clutch. You all really have me thinking about the Mcleod RXT twin setup now though. Both seem to be very good products with very happy owners. Decisions decisions. Link to comment Share on other sites More sharing options...
que4dog Posted December 20, 2012 Report Share Posted December 20, 2012 Yeah I just ordered the RXT. I hope it will last for a reasonable time. Link to comment Share on other sites More sharing options...
RR07SHELBY Posted December 22, 2012 Report Share Posted December 22, 2012 I installed a Mcleod Twin Disk RXTkit last week. It's has an extremely easy pedal and was a very easy install. Link to comment Share on other sites More sharing options...
marsh2o Posted December 23, 2012 Report Share Posted December 23, 2012 I just had the SPEC SS installed last week, along with a DSS CF driveshaft. The clutch (and the aluminum flywheel that comes with it) are a great improvement over the 2010 TSB clutch replacement that I had done several years ago (and which lasted only ~7K miles, before it too started slipping) and the SPEC is absolutely smooth quiet under all conditions. I've read about some people who have had problems, but I suspect that poor installations are responsible for many of these. Mine was done by my local Ford dealer (McRee in DIckinson, TX).

enormous Posted December 23, 2012 Report Share Posted December 23, 2012 I put a Mcload RXT in my 08 back in June and I highly suggest this clutch. Lighter than stock and handles my 650 RWHP nicely. Link to comment Share on other sites More sharing options...
Chris_in_PA Posted January 1, 2013 Report Share Posted January 1, 2013 Got about 23k miles on my car, and just started slipping, but only when one hits the accelerator and you can hear it slip (as well as the tach jumping up). Having our local speed shop (same guy did my 1 pc drive shaft, 3.73 gears, rear lower control arms, tune, and ran on their dyno (449 HP at the rear wheels). Am leaning towards the McLeod, however Centerforce offers he clutch, twin disks, and flywheel for about the same price. Any thoughts on the Centerforce? Happy New Year to all...will be visiting Carlisle next year....(live down the road from it) Link to comment Share on other sites More sharing options...
Firekiller Posted January 1, 2013 Report Share Posted January 1, 2013 Yo cant go wrong with either the Spec or the mcloud RXT. I just put an RXT in this past summer. I run 800hp and no problems out of it. Break in was smooth and a night and day difference over the stock one. Link to comment Share on other sites More sharing options...
mcate Posted January 14, 2013 Report Share Posted January 14, 2013 Who has the best pricing on an RXT? American Muscle has it for $1299, & I can get 6% off that for being a member of Themustangsource.com forums. Plus they offer free shipping.

Shelby73 Posted January 22, 2013 Report Share Posted January 22, 2013 I have an Mcleod Rxt ever since my stock one looked like a camp fire in stop and go,traffic to a car show. Love it!!! Feels great and not a single prob. Hardest part is driving like granny during break in period. Highly recoment this product. Link to comment Share on other sites More sharing options...
TexasShelby Posted April 19, 2013 Report Share Posted April 19, 2013 I have had an RXT Twin for 2 years with zero issues so far. That's longer than any of the other OEM clutches lasted. Link to comment Share on other sites More sharing options...
msbmustang Posted April 25, 2013 Report Share Posted April 25, 2013 I had an RXT put in last year and it feels great but it makes a "squeak/slip" sound going into 1st and sometimes second. It feels great though and takes hard shifts with ease. McLeod could not answer my questions about the slight noise so I just live with it. It is not as bad a noise as the 2KRPM harmonic noise from my Aluminum one piece driveshaft! I do really like the way it feels in spite of the noise.

2010KonaBlueGT Posted April 13, 2015 Report Share Posted April 13, 2015 I don't have any personal experience but have seen this one in person at Shelby Las Vegas. It's new but looks like something better than the other offers out there and it's direct from Shelby American. http://www.shelbystore.com/product-p/RS100201CA326KB.htm Phill Link to comment Share on other sites More sharing options...

08KR525 Posted April 13, 2015 Report Share Posted April 13, 2015 I've been researching Ace clutches. I believe they are manufacturing clutches for Shelby now. They are known for their racing clutches. Their materials and workmanship seem top notch. Link to comment Share on other sites More sharing options...
