Race Ready. When you're shopping for a flywheel for your Mustang GT, a SPEC Billet Aluminum flywheel is pounds lighter than your stock flywheel, meaning less rotational mass and less time and effort to get your flywheel moving when you romp on it at the starting line. The result? Your peak horsepower is delivered faster with lightning-fast throttle response and class-winning quick shifts.
Premium Quality. When you're adding a new flywheel to your Mustang GT, 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.
Please note that SPEC part# SF46A is the same as SPEC part# SF64A.
