    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.

    How is this flywheel as a daily driver in traffic?

    khankerson528

    • 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?

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

    eddie

    • 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.

    • The Exedy Lightweight Racing Flywheel will use the same balance weight as the OEM flywheel, allowing the stock harmonic balancer to be used.

      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.

      Awesome product, must have basic mechanical knowledge. The gains are immediately noticeable, spin up is super fast and gained 10 mph upper end cause of less drag per rotational mass (RPM's). Severely impressed and would recommend to others.

      aggressive and snappy

      This flywheel is a perfect fit. matched up perfectly with my exedy mach 400 stage 2 clucth that I purchased along with it. only con to the install was getting the guide pins in the flywheel but if you have some knowledge then you know they provide no physical use other than to line up the pressure plate. that being said you really don't even need them. along with the clutch replacement, this took about 9 hours from start to finish, but the tranny was dropped by hand not using a jack. jack would have been a lot easier. After all, i'm happy with my purchase and it is a great improvement to any mustang with basic bolt-ons and a tune.

      Great product. It was a big upgrade compared to my stock one. Had a local shop install it along with the Exedy Mach 400 stage clutch. There is a huge difference once I drove my car again. I would definitely recommend this along with any Exedy clutch.

      A combination of Flywheel and Stage 2 Clutch

      After blowing the original stock (80 mile) throw-out bearing, it was best decided to save some money and replaced most of the front drivetrain parts since the car had to be in a shop anyway. Before putting the car back on the track, I had replaced the flywheel, full clutch and fluid line and then added a standalone reservoir for the clutch fluid: Exedy Lightweight Racing Flywheel - 6 Bolt (96-98 GT; Late 01-10 GT) Exedy Mach 400 Stage 2 Clutch w/ Hydraulic Throwout Bearing (05-10 GT) McLeod High Performance Hydraulic Clutch Line Upgrade (05-14 V8) Shelby Iso-Clutch Remote Reservoir Kit (10-14 All) So it’s hard to give a review of one product, when combined it makes the world of a difference. I’m past the 750mile break-in and already had it back on the track so here’s my honest option: The combination of Exedy Flywheel and Stage 2 Clutch was a perfect pair! What I significantly notice is how easy it is to get the car rolling. If you release the clutch extremely slow while barely making over 1,000 rpms, the car actually engages and moves rather than the underpowered sputter that used to happen, wonderful for NJ traffic! The combination also helps with the initial launch as well, where if you released the clutch late during an rpm drop the car no longer does the underpowered sputter it used to. There’s noticeably a lot less lag in the lower rpms and the peak level feels a lot smoother going from mid to higher rpm’s. The bite on this combination is hard, and the rear tires spin when slamming it from 2nd into 3rd. Another obvious sign was how quickly the car stars up from a cold-start when sitting outside overnight. The McLeod clutch line upgrade made a drastic improvement as well. Not only does the clutch petal itself feel much smoother when engaging, but I’m fairly certain that it’s transferring the fluid consistently enough to know exactly where and when the clamping is happening, I seemed to reduce the amount of over-revs I used to have. And lastly I spent a good 6 hour day on Englishtown’s road course and had no problems whatsoever this time with the gears getting “sticky” and difficulties with shifting into 3rd while near redline at high temps. The clutch felt solid and dependable the entire time, I’m assuming this was also due to the fact I installed the Shelby Iso-Clutch Remote Reservoir Kit, which by design was supposed to separate the clutch fluid from the hot brake fluid. It didn’t cut down on the beak fade about 2 hours in but I did have very clean and consecutive shifts which was one of my original problems after spending hours on the track with the stock setup. I don’t have a single complaint. American Muscle sent everything within days of ordering with no problems, and “Krazy House Customs” who did the install for me said they didn’t have any issues at all. I would definitely recommend these parts to anyone who needs either their stock flywheel or clutch replaced.
