Now that we all are getting some time and miles on our cars I was curious about the life expectancy on the RXT.? Anyone have some insight on this? Also when it is time to replace I am guessing it is like any other clutch...disc, PP, T-bearing, replacement needed. Can the lightened flywheel be resurfaced or have to be replace?

We've been using the McLeod RXT clutches on all of our build here for years now and have had excellent results with them. I'll say with confidence that no one has run as many of their clutches in their shop cars or have sold as many RXT's as us.

As far as life expectancy goes that's kind of tough to say. For a stock to 700rwhp car I could see the clutch lasting a very long time unless it see's hundreds of passes at the drag strip. At that point obviously you'll see a shorter life expectancy. Same goes for cars making upwards of 1000rwhp and raced often you'll definitely see a shorter life span on it than on a car making less power or not driven as hard.

For the install we'd recommend the RXT with their lightened steel flywheel, pilot bearing and a set of new flywheel bolts. Might be a good idea to do an upgraded clutch line at the time of the swap since the trans will be down and you'll have access to it. The lightened steel flywheel can also be resurfaced.

Here's a few videos of our cars which all run the RXT. As you can see we've got lots of experience with these so if you have any other questions please feel free to give us a shout.

what about the RST and lightweight steel flywheel?

 

[Derek@Lethal]

The RST is fine for a bolt on application and the lightened steel flywheel will almost always be recommended unless the cars primary purpose is road course duty (then we'd move you over to the aluminum flywheel). Drag racing and street duty will want to go with the lightened steel flywheel in almost all applications.

Also to add on to what Jared said, the RST and RXT clutches are rebuildable so there is no need to purchase a completely new clutch kit when it's time to service the clutch. Unless something got completely fubarred during usage to where it cannot be serviced, it's going to cost about half of what the clutch kit costs to send it in for a rebuild instead.

Hope that helps, let us know if you have any other questions.

The RXT is a great clutch, heavily recommended.

I need a little advice, I have a 2015 GT that has been converted to a non-street HPDE/SCCA T-1 track car, I am a little suspect of the factory clutch at the extended RPMs it will be seeing. I will do the GT350 IM soon and will be moving the rev limiter from the 7200 to 7700 to take advantage of the change. The car will never see street use, will never be launched hard from a dead stop, will only see track time and it will operate in an RPM range of 4500-7700 for most if not all of its life. I cannot add any real power adders and stay in the class I intend to run, so that means my power level will be from 450-500 crank HP. I have owned several twin disk cars, however this is my first Mustang. I do not like the feel of a puck style friction plate so was looking at the RST with Aluminum Flywheel.

Some questions for you:
1. Would you recommend the RST and AU flywheel for my application?
2. Would you recommend any other clutch flywheel combos?
3. I have seen specs for the steal flywheel but how much lighter is the aluminum unit?
4. Is the RST quiet when in neutral? I am not a fan of the clank clank of many twin disk with floating plates.
5. Have you guys looked at running the GT350 twin disk on a GT with an aftermarket flywheel? Is it possible?

Thanks for your time and I appreciate whatever input you have to add.

1) For a stock/bolt on car, yes, RST is fine
2) Maybe a single disc Mcleod Street Extreme if you don't mind a heavier pedal
3) Aluminum flywheel is going to be about 11 lbs lighter than the lightened steel flywheel and 17 lbs lighter than the regular steel flywheel.
4) RST is relatively quite but all twin discs will make a little noise due the the floater plates
5) No, we have not looked into doing that as the construction/assembly/balance is completely different than the 5.0 application.

In the first video of the 15 is that with a stock mt82 with the clutch upgrade? If so thats insane:eyebulge:

Stock MT-82 with a McLeod RXT!! :cheers::cheers:

 

[JadedGT]

Do you recommend upgrading to the Tremec transmissions from the MT82 ? I can already feel my stock clutch is only going to last a few months now that I am pushing 700+ HP at it. The MT82 and Tremec use different splines so need to make a choice and go with a new trans and clutch / flywheel or just do the clutch / flywheel.

 

[Brian@Vossen]

what gearing were you running on your 15 with the 9 second pass?

 

[LethalPerformance]

I believe we were running 3:31's.

We've had very good success with the MT-82 so I'm not going to jump at telling people to swap out of them. With that said we do have customers who tend to like the strength of the Tremec transmissions better for higher HP applications and make the swap.

From personal experience though our MT-82 cars have held up very well. :cheers:

Thx! I am just going to go clutch and flywheel for now with the RXT. Later may upgrade the transmission.
