Review & Installation 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 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.

Fitment: 1996 1997 1998 1999 2000 2001 2003 2004 2007 2008 2009 2010 2011 2012 2013 2014 Details

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.

KeithB

  • 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.

    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.
