Review & Install Video

Hey Justin with AmericanMuscle.com here and welcome to my detailed breakdown of the Exedy Lightweight Racing Flywheel available for all 96 and newer Mustang GTs. Exedy is no doubt one of the biggest and most trusted names in stock and performance clutches and flywheels. They are one of the biggest OEM manufacturers of clutches and flywheels, and their support for the aftermarket is just as big. If you want to learn more about Exedy’s lineup of clutches, flywheels and clutch accessories, all you have to do is simply click the link below to head back to AmericanMuscle.com. So why would you want to go with a lightweight flywheel like this Exedy here? Well, whenever you’re upgrading your clutch, we strongly recommend upgrading your flywheel as well for a number of different reasons. The most obvious reason, it’s going to be much lighter. In fact, we do have a stock S197 flywheel here, along with our scale, and that weighs in at roughly 22.5 – 23 lbs, compare that with our Exedy flywheel, which does weigh about 16 lbs so depending on your application, you’re going to be shaving off about 6-7 lbs of rotational mass from your drivetrain. That’s huge, getting rid of that much mass from your drivetrain when it’s rotational mass, means the engine is going to feel more responsive, it’s going to rev quicker, and as a result your car is sure to accelerate to red line a little faster. OF course if you did want to learn more about the benefits of a lightweight flywheel you can always give us a call at 855-422-7439, or shoot us an email at support@AmericanMuscle.com. In addition both the SFI certified 6 and 8 bolt flywheels are made from solid one piece chromoly steel forgings, making them extremely strong in addition to being lightweight. Since they are one piece, all the ring gear teeth around the outside here are actually part of the flywheel itself, as opposed to other aluminum aftermarket flywheels which do have the ring gear teeth pressed onto the flywheel, which can be a known weak spot for failure down the road. Another unique feature of the Exedy flywheel is that they incorporate a special design into the flywheel itself to enhance air flow to both the clutch disk and the flywheel surface area. This is huge because as you may or may not know the biggest enemy to any clutch is excessive heat. Excessive heat will cause your clutch to start slipping like crazy and eventually it may glaze over possibly causing permenent damage to both the clutch disk and the flywheel itself. Whenever installing a new aftermarket clutch we strongly recommend going with an aftermarket flywheel of the same brand. So obviously if you’re going with an Exedy clutch we recommend going with the Exedy flywheel here just to ensure fitment and operation. It also makes sense to install both at the same time since obviously the trans will need to be dropped to do both. If this is something you haven’t done before, we recommend getting this one done by your local shop, on the other hand if you do this kind of thing all the time and you have access to all the right tools, just leave yourself about 4 hours or a nice Sunday afternoon in the garage to get everything bolted up, and don’t forget to follow the recommended manufacturer break in procedure for your clutch, before you really start beating on the car. Exedy’s lightweight racing flywheel offers a solid one piece chromoly construction, that reduces the rotational mass of your drivetrain , all of which results into a freer revving, more responsive engine and of course it can be found right here at AmericanMuscle.com, and if you should have any questions on what flywheel you need for your application, whether it’s 6 or 8 bolt, just give us a call at 855-422-7439.

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 1996-1998 GT, late 2001-2010 GT and Bullitt Mustangs with a six bolt main. This the perfect companion to your new Exedy Clutch.

Technical Note. This Exedy Flywheel is designed for the GT Mustang's with a six bolt main. 2001 Mustangs with production date after 06/01 have a six bolt main.

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.

what is the actaul weight differance between stock flywheel and the exedy flywheel

trannygod1980

  • I weighed the two and the stock flywheel weighed 22.5 lbs, while the aftermarket exedy flywheel weighed 16 lbs. It is a noticeable difference, especially because weight is cut out from the edges.

Only Compatible with Exedy brand clutches? I plan to purchase the McLeod RST Twin Disc clutch since my clutch is starting to slip, will this flywheel be compatible? Thanks, Drew

OutlawGT

  • You can use another clutch as long as they are the same size as the flywheel. I just contacted Exedy on 7/9/15 and they confirmed I can use another clutch with this flywheel.

    Since you're in there

    I was replacing my clutch and since I had it all apart I figured I'd replace the flywheel too. I liked the idea of the strength of steel and the lightweight part for less rotating mass. It is an interesting fit as it'll only fit one way and that can take some time to find the right way. But I did notice the engine revs faster now and it seems to be working pretty good.

    Looks Really Cool

    I received this flywheel as an upgrade from Exedy and did not buy from AM. I figured I'd share my experience with it here. Revs up much smoother and quicker. Hard to tell how much performance gain I got because I installed a CAI at the same time. But between the two of them I saw a nice gain. Like they say, every bit counts!

    Great lightweight reliable flywheel

    I blew out my stock clutch and flywheel so I decided to buy an exedy stage 1 clutch and this matching steel flywheel for my 2002 GT 6 bolt main. I am very pleased with this flywheel, after weighing the two I can tell you that the factory flywheel weighed 22.5 pounds, and this lightweight steel flywheel weighs in at 16 pounds. This is a noticeable difference and the best part is that the weight is removed at the edge of the flywheel; due to physics that is actually a better place to remove weight compared to the center of the wheel. Because it is a spinning object, removing weight from the outer edge will have a big effect, and after revving up my engine I can tell you that yes indeed this lightweight flywheel increases how fast it revs. If you want your engine to rev even faster you can also buy an aluminum drive-shaft, however this flywheel alone is a great improvement without making your street prowler hard to drive.

    Works and Looks Great

    I installed this flywheel with the Exedy Mach 500 clutch. Very nice flywheel. Remember to install the dowel pins BEFORE you put the flywheel on the car! I had to take off the flywheel because installing the dowel pins is not practical if the flywheel is on the car. A trick I used was to cool the dowel pins using an air duster by inverting the can. This helped to hammer in the dowel pins. The flywheel comes with an oil on its surface so make sure to use brake cleaner to clean it before installing the friction disk and clutch cover.

    quicker revs

    This light weight flywheel feels like bolting on 20hp! The engine pulls stronger from 2500rpm on up. You will notice the difference! I paired this with the Exedy Mach 400 clutch, Steeda cable and quadrant, and the SR firewall adjuster. Also put in The Ford Racing throw out and pilot bearings. It's a perfect combination of parts. Go baby go!!!

    wow! what a difference .

    this review is probably a little premature . I just had this installed and only have about 11 miles on this setup . this fly wheel with Exedy stage 3 clutch and steeda quick release clutch quadrant and SR firewall cable adjuster Ford Racing roller pilot Ford Racing clutch fork and Ford Racing Performance throw out bearing. the previous clutch was a spec . granted it was old and worn out and very hard clutch. it gave my left leg a heck of a workout . with this new setup I almost put my foot to the floor board. now it's so light and easy and the shift so easy and smooth and quick . so far I would say to setup is awesome . I will write another review when I have broke in the clutch and put some hard driving on it . so far very happy with the setup .

    Awesome Flywheel

    when i got it this flywheel it was in great condition. there was no cracks or dents. The weight difference between the stock flywheel was minimal, but there was a noticeable difference. Installation took me about a day to install along with a new clutch, but the flywheel was a perfect fit. i had no problems. If your looking for a new flywheel for your GT go for this one.

    Great product

    Wasn't expecting any real performance gain from this flywheel, as it's not much lighter then stock, but it fit perfect with my Mach 400 clutch, and it is actually somewhat noticeable. Would suggest this to anyone who wants a quality product without shelling out $400 for just a flywheel.

    Great Light Weight Flywheel

    I used this with my stage 2 Exedy light weight racing clutch, I could not believe the difference in the feel of the clutch. It shifts so much smoother revs up so much faster with great acceleration and has great bite for the drag strip. Makes your drive-train spin a lot freer and lets it last longer and huge difference in performace!

    Best Fly Wheel

    The fly wheel looks beautiful and has nice size holes taking a good amount of weight off from the outside. This wheel was built very well. Its nice and strong as it should be. I think this wheel is giving back about 2-4 hp/tq at the wheels witch can not be felt. Thant's why i gave it 3 stars for performance gain, but none the less its a good gain of free hp/tq. Cant really say for fitment. i can only assume it was perfect. My mechanic installed this pretty fast. For bang for buck lets just say this wheel better last for a long time.

    Much better then stock

    I've installed this and the Exedy clutch on two different 02' GT's. After about 150 miles the clutch breaks into normal feel, still don't want to romp it around till around 5-750 miles in my opinion just to make sure everything has a good chance to break in. If you're wondering on work time it takes; It took me around 10 hours of straight work with one mediocre friend assistant. Mainly because I had a few complications getting parts off. The main problem is the starter, that thing sucks if the top bolt is on I found it easy to remove the top half the starter then put it back together once it was off the car. This is a great flywheel none the less. Very noticeable RPM increase and decrease in neutral and the car is way smoother when shifting, grabs nice and tight. Way better then the stock one. I paired this with the Exedy stage 2 clutch and it is honestly so smooth I love it.

Aside from boost and a whole different exhaust note, the car revs faster. I use this on 2 supercharged mustangs I own. Both 450whp 2v's. Recommend this flywheel
