Aluminum flywheels have been used for many years for increasing performance. From the earliest days of racing and street build-ups, the world’s best engine builders have been installing aluminum flywheels to give their engines the needed edge. Fidanza’s aluminum flywheels are significantly lighter than OEM equipment, which results in quicker rev’s and more horsepower to the wheels!
All Fidanza flywheels are CNC machined to ensure the most accurate dimensions and the best possible finish. Fidanza flywheels are recommended for auto-cross, road racing and street use. (Because lightened flywheels do not store as much inertia, they are not particularly suited to hard launching, such as what is required when drag racing. For this reason, it’s not recommended for them to be used for serious drag racing applications.)

I am using flywheel along with a SPEC stage 2 clutch, and have had clutch chatter issues. After only 500 miles of driving, the vibration was getting to me, so I had it pulled and checked by a machine shop. It had a large hot spot that was 10 thousandths high or so. I sent the flywheel back to Fidanza, and they put on a new friction surface free of charge. Now it is back in the car, and for the first 200 miles it was ok, but then the chatter returned. I don’t know if it is just my combination of clutch and flywheel, or what. Anyway, it does take a little more gas to get moving. With the clutch being a grippier clutch I usually gas it to 1500-1800, then slip the clutch a bit. This is in a M6 with 3.42 gears. I’ve gotten use to the mild chatter, and you can tell a difference in how quick the car revs. No doubt a performance increase, but if I was to do it again, I’d probably get a lightweight flywheel that had a segmented surface to avoid the possible warping issues.
