McLeod Twin Disc RST clutch WOW

[younggun04]

Ha you guys are to much... I will post up if i ever run into problems with my RST. I got into it pretty hard last night for the first time since break in. Powershifting has never been so easy and the clutch didn't even blink. The only thing smoking were my BFGs! Of course my car is about 475 RWHP. So for now I recommend RST all the way but I am biased

Yep, the RST will work great at your power level. :beer:

Sorry If you took that comment the wrong way, I was not trying to be a douche. I was just trying to prove a point that this clutch in a 700 RWHP car would only work well if the car sat in a garage. It was not a personal attack on you but now that I re-read it I can see how you took it and I apologize. Sorry I might have been a bit of a dick since you completely disregarded my opinion without even looking into my suggestion. I knew you were going to regret your decision and that's why a pushed the issue further. When ever I get suggestions that's when I start to do my homework and try to confirm what was suggested. In this case you came off pretty dead set on the RST. Which i found to be a bit odd since price difference was only 200 bucks. But now I see that your main concern was street drive-ability which is valid. But you could have at least ask around about it before disregarding the unit base on assumption that it was poor in a street application that's all.

I know what you mean by weeding out the Fact from Fiction. For me I really don't like to relay information that I have read. I like to post based on my own experiences with Issues and Parts.

If you can find some of my older posts on the subject I was skeptical about the RXT after what happened to my RST. But now that I have put it through it's paces I am confident enough to share my findings.

I am glad you went with the RXT you will not be disappointed. No hard feelings here and good luck with your purchase. :beer:

Thanks man! I hope it performs as well as everyone makes it out to be. :beer:

I am so glad to hear all this good info on the RXT. I am slapping on a 2.8KB Mammoth next year and upgrading.

Matter of fact, I put in a call to Matt at Lethal a couple of days ago. I am awaiting a quote from him on my package and if the price is right, I am purchasing this bad boy.

We got my RXT from Lethal and they are the ones that my tuner confirmed the slipping issue of the RST at higher power levels. They had the slipping problems on their test car at the track and it was fixed after the RXT. For those "happy" with the RST and pushing under 500 WHP, don't be surprised. The stock clutch could make you happy at those power levels. None the less, still made a good choice with the TD system.

If anyone is going higher than 600, don't take a chance and go RXT.

And for those arguing, you're all XXXXXXXXXXXXXXXs that don't know crap about the origins of beer. :beer:

No derail here... This thread is for you guys! Looks like sleeper04 made the right decision because of it. I hope many more see this thread so they too can see what they're missing out on

My RST was able to handle a whopping 800 or so miles and 1 track pass it slipped on the second and burned up and smoldered for a very long time after, everyone thought that my motor had blown it was so bad. At first I thought my car was on fire. Very disappointed in it to say the least. But it was a really nice clutch while it lasted. Sad thing is I was assured by a Mcleod rep. after the clutch let go that the RST could handle my power level and take being run at the track the very rare times that I go as long as there was ample cool down between runs so I put another RST in my car I believe now this was ill-advised. Should have just kept the stock clutch in it since it was still good and doing well or put it back in after the first RST let go. With only 11,500 miles on my car with since 2004 an avg of 915 miles driven a year, and maybe 1 track visit a year or 1 every other year I would have thought the RST rated at 800hp could handle this.

Im going to revive this. I see the stock flywheel is the mcleod aluminum. for those who have ripped it out themselves, what is the shape of the back of the flywheel, or the motor side? Is it shaped almost like a air cleaner lid on a carbed car? So it's not totally flat like most, it is almost cone shaped? THat is how my stock mcleod aluminum flywheel is in my saleen extreme, and one guy at mcleod said that is one flywheel you cant use with the twin disc due to the center having that concave shape thus not providing enough friction material for the smallerr twin discs. Another guy there said it will work but it won't be making full contact but at my power levels I shouldn't have any problems and it will be more thern enough? I am stock and make about 425 to the flywheel.

So have any of you guys used the stock flywheel and is it shaped like i said? THanks,

Just to clarify we've never run an RST. All of our cars run the RXT and have never experienced any slipping issues.

Thanks, Jared

For the 03-04 Cobra you can re-use the stock flywheel with the Mcleod RST/RXT and it will work well without any issues. However the stock flywheel on the 03-04 cobra is similar to the 05-10 Mustang GT stock flywheel in that the center section of it is about 6.75-7" wide. The reason for that it that both the 03-04 Cobra 11" clutch and the stock clutch on the 05-10 mustang GT have larger hubs. When going with a twin disc clutch such as the RST/RXT which uses smaller discs that larger center section creates less disc to flywheel surface area. So the same way we recommend most 05+ mustang owners who want an RST/RXT to go with an aftermarket 99-04 flywheel we'll basically recommend the same thing for the 03-04 cobra guys. The aftermarket flywheels for the 99-04 cars such as the Spec and Fidanza ones have around a 6.25" center section. That provides for more disc to flywheel surface contact giving you better performance and longevity with the Mcleod setup.

Hope that helps explain it a little better.

About to order the RXT and I need a flywheel, which one do I order?
Thanks

Good stuff! I did not know this, and prior to this, I really like what I have heard about that RXT so far.

If you have an 8 bolt setup than any of the Mcleod or Fidanza 99-04 8 bolt flywheels will work. 463458, 463408, 563408, 186481, 286481.

If you have any other questions please feel free to give us a call.

Thanks, Jared

Thanks for response. Makes sense. Makes me think my flywheel is in a similar boat as the one guy told me I could use it but it won't make full contact. I guess it could effect everything, longevity, performance, driveability. Maybe I will stick with my plan of going with a spec 2+.
