    Review & Installation Video

    This is the Exedy lightweight racing flywheel for the 2015 and newer GT Mustang. You're gonna wanna check out this flywheel if you're looking for a new flywheel to pair with an Exedy racing clutch. Exedy flywheels are designed to be paired with Exedy clutches, and normally, when you're shopping for a new clutch, especially a higher performing clutch or one that's made to handle a higher horsepower setup, you really wanna pick up a new flywheel instead of resurfacing your stock one. Now, the install for a flywheel is gonna be a difficult one. Normally, you're installing a new clutch at the same time as the flywheel. You can expect a full day of work in the garage and a three-out-of-three wrenches on the difficulty meter. When you're shopping for a flywheel, you have a few different options when it comes to materials, usually billet steel or billet aluminum. Sometimes, you see lightened aluminum or lightened steel. You wanna make sure that you pay attention to the material of the flywheel because it's gonna make a considerable difference in the drivability of the car, and the life of both the clutch and the flywheel. The choice between steel and aluminum really all depends on what you plan on doing with your car and your preferences. This flywheel is made from billet chromoly steel, and it's lighter than the factory flywheel, about four or five pounds lighter, so it's gonna help with inertia and give you a little bit of a different drive than the factory flywheel can. This is stronger than the factory flywheel, too, which you will need if you're upgrading your clutch for horsepower and torque reasons. It's also SFI certified for those guys out there that are looking for that certification. If you guys have ever seen a flywheel before, you can see that this one looks a little bit different than most. Usually, they're more solid than the Exedy one is, so one drawback for the steel flywheel can be that it has limited heat dissipation. This flywheel is designed like this to give extra ventilation and allow for better heat dissipation. The openings here are larger than what you normally see. Normally, you'd see a few smaller holes, but the Exedy racing flywheel has these larger oval-shaped holes. Exedy really made this flywheel to be versatile. It's lighter than the factory flywheel, so you can get the benefits of a lighter flywheel and the easier revving and RPM increase. You also have the stronger materials, so it'd be safer with increased horsepower, especially in those higher RPM's. And you have the ventilation, more ventilation than what you'd normally see with a steel flywheel, for those of you out there that are looking for racing performance and needing the heat dissipation. When it comes to price, you can expect to pay just over $350. This is pretty standard for a steel flywheel. If you're looking for an aluminum flywheel, you can expect to pay a bit more. The steel flywheels are a bit more affordable, but like I said earlier, it really all depends on what you plan on doing with your car and what you're personally looking for. As far as the install goes, this is gonna be a difficult one. It's gonna be a day in the garage, and it's gonna be a three-out-of-three wrenches on the difficulty meter. It's a lot of work, so you need some experience to get this job done yourself, and a lift is gonna 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. You've gotta drop your trans, which means you'll need to unbolt your exhaust and drop it from mid-pipe back, and your drive shaft, 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 and the flywheel. Once the stock clutch is out of the way, you'll need to install your new flywheel and clutch. If you're installing the new clutch at the same time, the instructions will tell you how to assemble your clutch. After that, you're looking at needing to bleed the clutch line, which can take a little bit of time, but it isn't difficult. The only other thing that I wanted to mention here is to make sure you follow the break-in period with the clutch if you happen to install a new one with the flywheel. That's gonna wrap things up for the Exedy lightweight racing flywheel for the 2015 and newer GT. As always, you can check it out more online, right here at americanmuscle.com.

    Peace of Mind. When upgrading to an Exedy performance race clutch resurfacing your old stock flywheel just won't cut the mustard. A brand new matching flywheel is a much better choice than resurfacing, as the flywheel will dictate how well your race clutch will perform, as well as how long it will last.

    Engineered For Better Response. Made from one piece solid billet chromoly steel forgings, Exedy Race Mustang Flywheels are specifically engineered to reduce weight and inertia for improved engine response. This Race Flywheel incorporates special design features to enhance air flow to improve the cooling of the clutch.

    SFI Certified. If you're using this flywheel in high performance or racing applications, SFI Certification is critical so you can run your Pony at the track or strip. And it's great for peace of mind even in a daily driver - at higher RPMs, stock cast flywheels have been known to explode.

    Application. This Exedy Racing Flywheel fits the 1999-Mid 2001 GT, 1996-2004 Cobra, 2003-2004 Mach 1, 2011-2014 GT, and 2007-2012 Shelby GT500 Mustangs with an eight bolt main. This is the perfect companion to your new Exedy Clutch.

    Technical Note. This Exedy flywheel has an 8 bolt main that is found in the 1999-mid 01 Mustang GT's with production date ending on 06/01, 1996-2004 Mustang Cobra's, 2003-2004 Mach 1's, 2011-2014 GT's and 2007-2012 Shelby GT500's.

    Please Note. Romeo built engines have 6 bolt cranks and Windsor built engines have 8 bolt cranks. If the 8th character in the VIN is an "X" its a Windsor block, if the 8th character in the VIN is a "W" it is a Romeo block. There is an exception to that rule as the 2001 Bullitt Edition Mustang feature a Romeo built engine. If unsure please check with your Ford dealer to determine if you have a 6 or an 8 bolt main.

    I’m hearing this may cause cel. Why is that and how to resolve it?

    LEE

    • The Exedy Lightweight Racing Flywheel may cause a check engine light on 11+ GT's if a crank position sensor relearn is not performed. The crank position sensor relearn is a part of the installation procedure, and any qualified installer should perform this as part of the install process.

    • The torque spec is 59-64FT POUNDS of torque, but, it is always recommended to replace flywheel bolts instead of re-using.

      Quality, SFI certified and lightweight.

      I reccomend this part highly to EVERYONE of AM’s customers. I can feel the high end gain, and would buy it again. My new Exedy Mach 400 clutch engages flawlessly, emits no vibration or noise, and grabs hard. Sure, the average person driving on the street won’t benefit in any single major way from this part as the naysayers have already told you, i’m sure! I conceed if your car is stock and you plan to keep ot that way, it makes little sense unless your flywheel can’t be resurfaced. For me it was well worth it, I was already doing a clutch job and it would have been the third time resurfacing my flywheel. I can say that my car feels significantly different between gears, It’s as though it carries more speed through the shift particularly 1-2 and 2-3. Normally between shifts there was a lag in power and this upgrade eliminated any lag it just revs and keeps going. As always there is a tradeoff and you do seem to lose some initial pep off the line or when you first floor it. My experience is consistent with the general conscensus as to what a lightweight flywheel does and the science behind it. Keep in mind our cars have traction issues at launch so this works to our advatage in my opinion. If you are like the typical AM customer your quest for more performance what you can do next or at the same time is add a lightweight driveshaft and gears to compensate for the loss off the line. These three mods really help to get our cars moving particularly when you have added all the bolt ons and want more. You can easily knock a half second or more from your ET with these three additions. If I still haven’t convinced you consider your car is a work in progress like most of the people who shop here at AM, why not upgrade to a stronger high performace part when you are already doing a clutch or transmission job? It just makes sense! After all your pony likely has things like gears already, or at least a handful of performance parts. So, tell me how can you go wrong with a new flywheel? Sure it’s not necessary, but really it’s the sum of all the little improvements that make this part worth it in my opinion. The flywheel reduces a few lbs. of weight, gives you peace of mind knowing it will stand up to aggressive/track use, can add an MPG or two, and will likely knock a tenth of two from your 1/4 mile run.

      Wrong part

      Bought this thinking it would fit my 2003 GT because the ifo I was given said that all Windsor motors used a 8 bolt fly wheel. After talking with AM I was told that not all Windsor motors are 8 bolt, but only dual cam version. I'll be putting in the new clutch and fly wheel next week. Sure hope they fit

      Need Recomendations for Pilot Bearing

      I got the package fairly quickly. That made me happy, however I ordered a Ford Performance Pilot Bearing and it just happens to be too small for this flywheel. I haven't been able to find any place that sells what i need. Any help is welcome. Until i find the right part i don't think i can give it the rating it probably deserves.

      Great quality, but a little heavy.

      The flywheel is constructed well. It performs great. My only complaint would be the weight. It is advertised as a "lightweight" flywheel but I could not tell a noticeable difference in weight over the stock flywheel. It did not actually put them both on a scale but a difference in weight could not be felt in handling them in comparison to each other.

      Great flywheel so far! A little pricey but well worth it. The acceleration is smooth and it revs up and a little quicker because it's less rotational mass. I paired it with the mach 400 exedy clutch for my 305 rwhp Mach 1 and I deff think its a solid pair together!
