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.

  • If the 8th digit of your VIN number is an "X", you have a Windsor block motor which is an 8 bolt crank.

What torque should be used when reusing the stock bolts to the flywheel?

MattK

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

    Top quality clutch

    I paired this with the stage 2 clutch kit also available from Exedy. It definitely revs up quicker, but the revs still drop just as slowly as they did with the stock anvil of a flywheel. I thought this was really weird and I did some research. It's actually not the flywheel's fault. It's the fault of the idle air control. (IAC) I have to say I was slightly disappointed that the revs still dropped so annoyingly slowly, but again, it's not the flywheel's fault. Besides, the IAC doesn't matter you're braking for a corner. The flywheel will still help you to slow the car down as long as you're in-gear. It's a quality product and I do recommend picking one up for a noticeable sharpening of acceleration and deceleration. I'm curious of how much more I would have noticed if I waited to pair it with an aluminum driveshaft. I'll find out asap and review that as well.

    Exedy lightweight flywheel

    I paired this with their Mach 600 clutch, did the 500 mile breakin then let her rip. The grip is amazing. I have the roush stage 3 675 hp upgrade on a 2012 gt and this clutch grips no problem. Very minor chatter at low rpm's, on a incline mostly, but not enough to bother you. I waited about 400 miles before having dealer perform crankshaft sensor relearn. If you keep it below 4k you won't get the cel light. When you do it will reduce power on you then light will stay on, then you can drive casual again. Even on a lift this is a full days work. I also used the ford racing pilot bearing instead of the one in the Mach 600 kit and ARP bolts on flywheel. lastly, I used this time to put a Barton shifter bracket on which does tighten up the shifting a lot. Much smoother.

    The exedy flywheel is much lighter than the stock flywheel and you can feel the difference in acceleration,you must also get exedy clutch stage 2.

    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.

    Direct bolt on (Windsor engines)

    Just got this flywheel installed at my local shop and I'm very pleased with this product and how easily it came together. Along with the flywheel I also installed a stage 1 Exedy clutch kit on my 2000 GT, I would highly recommend both these products. As far as performance goes this flywheel does free up your RPM's allowing to be more responsive throttle feel when accelerating at higher speeds. If your looking into swapping out your old flywheel and clutch I would highly recommend both these products as they do perform to customer satisfaction.

    Exedy Lightweight Racing Flywheel nice part

    The video says it all but if your concern is that it will throw things off balance when upgrading your clutch. The double sprung exedy pressure plate makes up the weight you save on the flywheel. It is about 6 to 7 pounds heavier So you don't actually lose any rotating mass. but you do gain about twice the clamping force. Also the flywheel pressure plate combo does not use 3 of the bolts that the stock setup does. BTW none of the exedy components give any direction so know what your doing or have someone who does help you.. This is Very Common in clutch installs and nothing new ..Just an FYI.
