Description
Race Ready. When you're shopping for a flywheel for your Mustang GT, your Cobra, or your Mach 1, if you're serious about shaving precious tenths off your laps a billet aluminum flywheel is a must-have for quick shifts and class-winning times. SPEC's Billet Aluminum flywheel is pounds lighter than your stock flywheel, delivering your peak horsepower faster for quicker starts and faster shifts.

Premium Quality. When you're adding a new flywheel to your Mustang, you want a premium quality part that will deliver both performance and durability. SPEC Billet Aluminum Flywheels are machined to a .001 tolerance (other brands are only made to .01) and designed and weighted for the perfect balance and surface to compliment your new clutch.

Protects Your Investment. When replacing your clutch you have two options: resurfacing your flywheel, or getting a new flywheel. Most times, getting a new flywheel is better than resurfacing, as the flywheel will dictate how well your clutch will perform, as well as how long it will last.

Rebuildable. A cheaper flywheel won't stay that way - SPEC's aluminum flywheels have a replaceable steel friction plate which makes this flywheel rebuildable. And this flywheel surface is also made from a special type of steel specifically designed to help your new clutch "bed in" properly and to promote superior grip - so this might just be the last flywheel you ever have to buy.

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.

Good price and flywheel

Installed with a SPEC Stage 3 clutch, firewall adjuster and quadrant on a 2004 Cobra. After the 500 mile break in period, the clutch grips well. Weight between the SPEC aluminum flywheel and stock cobra

Rev Happy!

Ordered flywheel, with Spec Stage 1 clutch and FRPP alum driveshaft. Just got the car back, and it\'s very rev happy... grabs R\'s super fast and makes the car feel pretty peppy, like new again!

    Good price and flywheel

    Installed with a SPEC Stage 3 clutch, firewall adjuster and quadrant on a 2004 Cobra. After the 500 mile break in period, the clutch grips well. Weight between the SPEC aluminum flywheel and stock cobra flywheel (also aluminum) is about the same, but stock does not have a REPLACEABLE steel insert. Very little in the way of directions for the two SPEC products I purchased. Overall, it has worked well with the SPEC clutch, and I bought it for the replaceable insert. It would be a more dramatic change on the revs of the GTs as they have steel flywheels, it feels stock on the cobras.

    A good investment

    My 98 cobra definatly revs faster since the install the biggest differance I can tell is how much smoother the engine feels at 5k and above I like it but it is a little on the expensive side for the amount of gain

    Spec Billet Aluminum Flywheel

    Awesome product and well worth the money. It makes the power feel like it comes on a lot smoother. This was one of the best mods that I have done to the drivetrain. I highly recommend this to anyone that is looking to change their clutch and flywheel. I cant believe how much smoother it is. I took my car out on a 100 mile road trip through some twisties today and I couldnt believe how much better the car felt.

    Loose Weight

    I wanted to take out the old to see what all I truly needed. My fly wheel needed turned, my schedule makes it impossible to get to the closest shop to drop off and then pick up. Thats the line I used with my wife. American Muscle came through, I recieved the new parts for the next week end. Thanks American Muscle. Thats free shipping by the way. I added the Spec 2 clutch. I have the fire wall adjuster, the feel of the new clutch is great, pedal effort is easier than stock. The iron fly wheel that came off just about cracked the floor, the Spec I put on with one hand. Serious weight loose, I would have weighed the two, but needed to keep peace in the house with the boss. I owe her a new carbage disposal. Make sure you put the dowels in from the back of the fly wheel with a punch. Great product, engine revs faster. The ablitiy to change the friction plate will make next time great, just order from American Muscle.
