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.
