    Review & Installation Video

    Review & Install Video

    Hey, Guys! Stephanie with AmericanMuscle.com. Here with a quick review of the McLeod RST Twin Disc Clutch. Rated to 800 horsepower for the 2015 and up S550 GT Mustang. We're going to cover a few things in this video like the components of this particular clutch and an overview of the install as well, which I can tell you right now is going to be a three out of three wrenches on the difficulty meter, since a clutch replacement is a lot of work. Most people are looking at taking the car to a professional for the install. The McLeod RST Twin Disc Clutch is going to be something that you should consider if you have an S550 GT with some modifications that's making enough horsepower to overpower the stock clutch. This clutch is rated to support up to 800 crank horsepower and thanks to the twin disc design, it keeps a very light pedal feel. Other heavy-duty clutches that keep the normal single disc design, that support power numbers this high, have a very heavy pedal feel. This clutch, on the other hand, is able to support high horsepower numbers with a very light pedal feel. If you compare this clutch to the stock clutch, the main difference is going to be the fact that this clutch has two clutch discs instead of one. The stock clutch has one disc and when you start upgrading clutches over the stock clutch but still maintain only one disc, you see things like different compounds that are more heavy-duty and able to handle more horsepower and torque. You also sometimes see changes in design, like a puck style clutch or basically, more friction surface area to handle the power. As you start to change compounds and material, you get a different type of engagement and disengagement, and a stiffer pedal feel. The RST on the other hand, has two clutch discs that are made from an organic compound, which happens to be a more forgiving compound. The old saying that two is better than one comes into play here, since these discs might not be very strong on their own, but when you pair them together they can handle a lot of horsepower and torque. The twin disc clutch is going to be able to dissipate heat better. You have twice the surface area to ensure you're getting a more positive engagement when the pedal is released since now you have two discs that are going to be separated by a floater plate. This is especially necessary for the street/ strip application of this clutch. And the best part, the pedal feel. I keep mentioning pedal feel, and a lot of the pedal feel has to do with the material of the clutch discs. Like I just said, these clutch discs are made from an organic compound and they're twin sprung hub friction plates. This means that there's a smooth engagement with very little pedal effort. Being sprung hub and having an organic surface material also means that the clutch has a nicer release characteristic, which makes it a good clutch for both street and strip applications. This clutch is designed specifically for the MT82 trans, which has a 23 spline transmission. It's going to come with your pressures plate, your clutch discs, a floater plate for in between the discs, an adapter ring, and a pilot tool as well. You will need to figure out what you plan on doing with the flywheel, though. You can always resurface your current flywheel but I'd recommend just purchasing a new McLeod flywheel because it'll mate with the new clutch perfectly and allow your clutch to function to the best of its ability. There are a few different types of flywheels that you can choose from depending on your application and what you built your car for. The only other thing I'd recommend picking up if you don't already have it is a steel braided clutch line. The stock one has all kinds of performance issues and if you're at the point of shopping for a twin disc, I'm sure you know what I'm talking about. When it comes to price, you can expect to spend between $700 and $800 for this clutch. Twin disc clutches do tend to cost more than a single disc clutch, even sometimes a puck style clutch, although they do tend to be close in price. The McLeod is more budget friendly than the RAM twin disc is, but the RAM does come with a flywheel while you have to purchase that separately with the McLeod. Depending on which material flywheel you want, you're looking at spending a few hundred dollars more. I'm sure you guys already expected this, but the install here is not easy. It's a lot of work, so you need some experience to get this done yourself, and a lift is going to be your best friend. If you don't have these things, it might be best to take the car to a shop for the install. Overall, this is a three out of three wrench install on our scale here and should take about four hours to complete. You've got to drop your trans, which means you need to unbolt your exhaust and drop it from the midpipe back and your driveshaft as well. You'll have to drop your starter and unbolt the bell housing to get the MT82 out of the way so you can get to the clutch. Once the stock clutch is out of the way, McLeod does tell you how to exactly assemble the clutch properly so you don't have to worry about that. The only other thing that I wanted to mention here is make sure you follow the break-in period with the clutch if you want the clutch to be smooth and have a long life. Wrapping things up here with the McLeod RST Twin Disc Clutch, this is a street application clutch that can handle some strip time as well. It's capable of holding up to 800 horsepower and maintain and very light pedal feel thanks to the clutch design and the organic compound that it's made out of. As always, I suggest you check this out more online for yourself and for all things Mustang, keep it right here at AmericanMuscle.com.

      Outstanding clutch!!!

      At the end of the break in period and this clutch is amazing. Solid hold and you can real feel the accelartion after each shift. I will stay that the pedal is not for amature or the best for stop and go on hills. The engagement on a 2015 GT is immediate and very short. I have yet to trying out on the track but overall I personally love this clutch.

      Clutch issue

      Supercharger addition produced too much torque for stock clutch so upgraded to the McLeod light weight steel flywheel and RST twin clutch. Great job handling the power now.

      Great product!

      The clutch is way better than stock one. It performs smoothly and leaves your clutch pedal very soft. However, after installing new clutch, when shifting from first to second and second to third a loud buzzing noise comes from undernearth the hood. I took it to a mechanic and he said that the noise is coming from my transmission as if there were a lose bearing inside of it. Mind you I kept the stock flywheel, does anyone have any idea if this noise has to do with not changing the flywheel as well?

      Regardless if your mustang is pushing anywhere near 800 hp this clutch is much better then the stock clutch that the mustangs come with. This clutch for the price is well worth it and fits perfect in the mustang.

      Read it if you have stock mustang

      So I bought this clutch and it work just fine but be careful I have been using it for 2 weeks now and kinda scared to break my gear. When shifting between 2nd and 3rd you will hear a knock in the back of the car I actually don’t know what it is yet.

      McLeod great as always

      Great clutch, I paired it with a McLeod lightened steel flywheel and after breaking it in last weekend I can say it definitely grips better than stock. I'm running it on a 2015 with just a jlt intake and an exhaust with a time for 93 but opted for the rst to hold with the forced induction plans over the winter. The petal feels slightly, almost unnoticably stiffer but the bite is instant. Chatter is to be expected under 2k rpms but that's nothing a louder exhaust can't fix.

      I have broken in two weeks with my 430 horsepower that is very hard to predict as it's a big disappointment. I recommend changing each piece when you want to change your clutch

      McLeod RST Twin Disk with Roush Supercharged 2015 GT

      Not completely broken in yet but so far is performing well. No slippage with 670 HP. Description says that an aftermarket flywheel is recommended, according to McLeod it is mandatory because the clutch diameter is smaller than stock and will hang over the inside surface of the flywheel. Has noise at low RPM's and high gears due to no springs on the disks. Can be avoided by keeping the RPM's above 1500. Also notice a little bit of shudder, most likely also due to no springs on the disk.
