    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.

        5 Top Rated Questions

        How is this flywheel as a daily driver in traffic?

        • This flywheel is going to be lighter which would cause the engine to rev quicker and the clutch to grab harder. This would be okay for use on a daily driver if you were looking for a sportier clutch feel.

        I was wondering if installing this lightweight flywheel with the Exedy Mach 400 stage 2 clutch would cause a stalling issue? I've heard that after hard accelerations or simply sometimes just putting your car into neutral with a lightweight flywheel, you're car may stall? Will this happen with this model on a 2002 Mustang GT?

        • Hello! It really depends on vehicle as it differs from one to another. Some people experience this problem and others do not so it is hard to say.

        what if my eight digit is a H would this fly wheel be compatible

        • If your digit is "H", you will have a 4.6L motor. The 4.6L motor is in the 2005-2009 V8 Mustangs. This will fit with that motor.

        • Yes dowel pins are supposed to come with an order of this clutch. If you order this clutch and do not receive dowel pins, or in general if you order anything and don't receive everything you were supposed to receive, please contact our customer service team right away so they can offer their assistance.

            Great upgrade

            I was apprehensive about a lighter flywheel having driven race cars in the past. I thought it would it would make the car less drivable on on the street (i use my car for track days and street). After it was installed I noticed no drivability issues. The car was more fun to drive both on track and on street. Reves cane quicker and lap times went down (i have the data logs to prove it. Definitely a worthwhile upgrade.

            Still in break in but love it

            about 400 miles on the clutch and flywheel for the break in process and I'm very happy with the results. car does rev a little faster. has a noticeably faster acceleration in 3-4 gear. overall I'm very pleased with the results so far. had a shop do the install and said they had everything they needed. I did have a nasty grinding noise on startup and they discovered the separator plate was an older version. got me the new version and now no grinding or rattle at 2000-2500rpm when cold!

            Box came smashed up, but everything inside looks fine. You’d think for the price that you would get new flywheel bolts too but that’s just a petty complaint.

            Flywheel

            Fit great and looked great. It revs a lot faster than before. I'm still in the break in period on the clutch so I haven't noticed any performance or acceleration differences but overall a good product to pair with the exedy mach 350 clutch kit. Make sure you get a pilot bearing puller tool before you start the project, it will save you time and a headache.

            Excellent Product

            Bought this back in July '18 to go w\ an Exedy Mach 500 Stage 3 Grooved Clutch kit to get installed in my '09 GT. Finally came time to get all installed after recently noticing clutch engaging very high in pedal travel (sign of worn clutch disc) and finding my clutch master cylinder had started leaking brake fluid out back beside push rod (OEM plastic unit). Took car to local Ford dealer (only place around that I trust w\ my car) Monday to get all installed. Got car back today and all is good. Clutch is now engaging very low in pedal travel and is grabbing very quick due to the grooved PP and it's increased clamping pressure but is smooth w\o any chattering so surface mating is excellent..... Weighed OEM flywheel @ 22.0 lbs....weighed Exedy LRF @ 15.2 lbs so shaved 6.8 lbs of flywheel mass off engine. Engine is showing no signs of low RPM rotational inertia loss on 1st gear takeoff from the flywheel weight difference so this is an excellent finding as drivability is fully retained but engine does rev up a little quicker which makes my car more touchy on accelerating smoothly (have a BBK 62mm TB installed which adds to it) off 1-2 and 2-3 gear changes so I may have to have the TB response rate readjusted in the tune to soften it's response a little more to compensate. Once I get the clutch fully broken in it should ease up on some of the grabbiness as well and become a little more controllable to feather on engagement. Would recommend this product to anyone who is looking to upgrade their clutch setup!

            Perfect match for Mach400 stage 2 Exedy

            I, like a few others were concerned that with my SCT tune and the lightweight flywheel it might be tougher to baby it into a 1st gear roll. It's no problem. The flywheel is just right. No stalls (wife stalled it once on her first drive). Revs quicker. Downshifts (rev-match) easier. The one thing I did notice, is that with the A/C on high the idle drops pretty low when the compressor cycles on and off. Hasn't stalled and I doubt it would, but with the heavier/stock flywheel it would just power right through those cycles without the slightest drop in rpm. No biggie though, just something you might notice. Great package. I had the Mach400 without the flywheel and it felt really good. Put the flywheel in 3 months later, felt even better.

            Gained 400 RWHP (Not really)

            It's a fly wheel. The transmission was getting pulled to replace the clutch, so we through one of these and a braided steel hose on it hoping to not have to pull it again at $350 a pop. I'm still breaking in the clutch, but I've only really noticed the RPM's dropping quicker. If it becomes noticeable after the break-in period I'll post back.

            Great product

            Exedy racing flywheel Installed in combination with the Mach 500 clutch and exedy clutch slave cylinder/stainless line. Clutch pedal feel is very easy; grandma could drive it. Grip is great, no slippage ever with 450whp. Revs much quicker than before; almost as much improvement as upgrading the driveshaft, but not quite. If I gave the driveshaft a 10 for making it accelerate quicker; this clutch/flywheel combo would get a 6. Where it really shines is driveability. Great product.
