      Review & Installation Video

      Hey everybody, I'm Justin with, and this is my review of McLeod RST Twin Disc Clutch, available in sizes for your '01 to 2014 Mustang GT and Boss, in addition to your '03 to '04 Cobra and Mach 1. In the world of aftermarket clutches there is obviously a ton to choose from and I think you'll find McLeod to be one of the more premium options in the world of clutches. Now they do offer anything from your bone-stock daily driver or light bolt-on car, all the way down to your thousand-horsepower strip monster.Now what we're looking at today is one of the big boys, the RST which is a twin disc clutch, and believe it or not, it not even the burliest clutch they do offer. They also offer an RXT, which is capable of holding upwards of a thousand wheel-horsepower. So with all that said the RST is definitely going to be a good option for those of you guys out there who are looking to make or already making big power through either forced induction or nitrous for your street-strip car or your dedicated drag car. Not so much for the cars out there with light bolt-ons or even stock. This thing would definitely be overkill.Now a twin disc clutch, for the most part, is a thing of beauty, because it's going to offer unparalleled holding capabilities with a pedal feel or effort that's not going to kill your leg in the process. Now the only downside to a twin disc clutch is usually the price, as they are not often cheap. The one thing I do like that McLeod has done to help keep some of the costs down here, at least with the pre-MT82 RST, is allow it to be used with any stock or aftermarket flywheel as long as the bolt patterns match up. Now both the Ram and Exedy twin discs here on AM, they do include flywheels, which is only going to increase the price. Now for the MT82 crowd, both the '11 and '14 GT and Boss owners out there, McLeod strongly recommends you use their RST with the McLeod flywheel for the best fitment, of course, here. Well that is going to increase the price, but as always, you have to pay to play.Getting into some of the specifics here with the RST we'll notice dual organic material friction plates here separated by the floater plate, the signature red McLeod pressure plate, and last but not least, the adapter ring. Now it's not uncommon to experience a little bit of noise at idle with a twin disc clutch here, and that will be the case with the RST. At least some of our customers have pointed that out, so be sure to check out those reviews if you haven't done so already.Installing a new clutch can be a little tricky if you've never done it before and especially if you don't have access to a lift, so for that reason alone I'm going call this one three out of three wrenches on the difficulty meter. I might knock that back to a two out of three wrenches if you do have access to a lift because obviously it's going to make life a whole lot easier. Figure the trans does have to get dropped obviously for this one, so we'll call it four hours or less from start to finish. And also another biggie here, make sure you follow McLeod's braking procedure for the clutch to get the most life and performance out of the clutch itself. So if you're looking for a proven clutch for high horsepower applications that's going to maintain great pedal feel and drive-ability, you have to consider the RST from McLeod, and you can find yours right here at

        Chipped clutch disc

        I bought this item after being recomend to buy it from American muscle technicians and after I bought this it’s been nothing but problems. After I took out of my transmission out of my daily car. I open up the clutch box to find that one of my clutch disc had a chip in it. I called American muscle and I told them that I need a new clutch ASAP since I cant go to work and how that’s my only car. The lady that I spoke to told me there’s nothing that they can do for me and I would have to send the old one back which I did and I was promised I was going to see it by Friday now the arrival date got pushed back. After calling again and complaining they still couldn’t do anything. Be carful what you buy they’ll tell you what you want to hear and American muscle does not care if that’s your only car

        Know what you’re getting.

        This clutch works fine although the engagement point is not where I prefer it ,but I will get used to that. My complaint is that the clutch makes quite a bit of noise between 1500 and 2000 RPMs under load and I am not a fan. Unless you are racing the car or moving into the upper 600 range of horsepower I would strongly recommend a sprung disc style clutch. I talked to McLeod and they said the noise was normal and I asked them if they would take it back and they told me no. Side note: DO NOT under any circumstances use in Mcleod throw out bearing! Mine was trash right out of the box and caused me to have to pull my transmission twice.

        Awesome clutch

        Installed the rst and Mgw X-Spec shifter and its is definitely tough getting used to it but I can tell it is going to be a monster after the shifter and clutch break in! Harder to pull away at 1st gear but just takes some getting used to. Clutch is awesome and peddal feel is super light!

        Jury still out

        Have not made it the 500 miles for break in yet so hopefully will get better. Shudder/chatter in reverse on a hill or on incline in 1st gear is tough to pull away without making entire car shake. Shifts are fine but have not shifted at high rpms as still in break in. Installed new throwout bearing along with Mcleod flywheel when doing clutch. High hopes will be better after time. Other reviews I have read mostly say it does. 2011 GT with Roush Stage 3 supercharger. Ratings kind of pointless at this stage but had to select something or review would not post

        Everything works great, bite is awesome. Only problem is with the dowels on the Stock flywheel, they did not line up with the clutch. After removing the dowels I rotated the clutch and found the spot that fits. I'm about 800 miles in with it, does make a shuddering sound when slowly accelerating, but not bad. I am now shifting at 7,600rpm with absolutely no problem.

        Must have mod

        I purchased this clutch in hopes it would fix a high rpm clutch sticking/lockout issue. No more issues. This clutch bites hard. It’s like having a new car. Shifting is Butter smooth and rev matching is so much easier. There is noticeable clutch chatter between 1200-1800 rpm but it doesn’t bother me. Also the engagement point is now at the top of the pedal. This took a WHILE to get used to, but all is well now.

      Hi, There is a comment: "Also when driving at low rpm's 1200-1800 there is a loud rattle from the clutch. I'm told this is a normal condition for a twin disc clutch." Is this true? Does the clutch normally rattle at lower rpms? Thanks

      • I had a RST in my o7 Shelby GT , and it was outstanding , I do not recall any noise ,,, if so it was not noticeable to me ,,,,,,,,,I tracked the car at Willow Springs and Laguna Seca and the clutch was excellent

      Has this clutch been installed and driven on? Does it include all pieces i.e.- the pressure plate, both discs. floater plate and adapter ring? I don't need the tool. Thanks.

      Can this clutch use the stock through out bearing or would we need to purchase a MCLeod?

      • While this clutch is capable of using the stock throwout bearing, we recommend upgrading if your car is making enough power to require this clutch, as the stock throwout bearing is most likely not up to the task.

      Will this clutch work with the Exedy light weight flywheel

      • We would always recommend pairing the same brand clutch with the same brand flywheel.
