      Peace of Mind. When upgrading or replacing your V8 powered Mustang's clutch you have two options, resurfacing your old stock flywheel, or getting a brand new flywheel. A new SR Performance flywheel is a much better choice than resurfacing, as it will dictate how well your new clutch will perform, as well as how long it will last.

      Billet Steel Construction. SR Performance Mustang flywheels are CAD engineered for excellence and precision CNC machined to strict tolerances from 1045 Billet Steel. Every flywheel is rigorously inspected throughout the entire manufacturing process to ensure that you receive the quality you have come to expect from SR Performance.

      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 SR Performance Billet Steel 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 clutch.

      Technical Note. This SR Performance 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.

        Good Flywheel

        Everything is great, but had to drill out holes a tad during install to fit on my transmission. they were about 1mm off.

        Billet still flywheel

        This clutch was much nicer than my original clutch and bit a lot firmer and quicker. It was the cheapest option but it went in nicely and it was solid.

        A good compromise between performance and driving ease

        I originally bought a lightweight aluminum flywheel made for my year, yet it did not fit so I was forced to purchase this one. I couldn't be more happy with my purchase, and although it's not a lightweight "racing" flywheel, it still feels very smooth within the car, on top of the fact that it is much easier to drive in stop and go traffic.
