Racing Beat Flywheel upgrade

Kentetsu · 03-10-2010, 12:46 AM

Another thing to consider is that, with the lack of inertia, you will need to slip the clutch quite a bit more when starting from a dead stop. This means the clutch will wear out faster, and you will be performing that maintenance a bit more often than with a heavier flywheel.

The general recommendation for spirited street driving and autocross is to go with a light steel flywheel. If the car is used strictly for track racing, then go aluminum.

Hope this helps.

^^^ Define "wear out faster". I had an Fidanza flywheel/Exedy Stage 1 clutch combo on my old car for 30k+ miles and still going strong before I sold it (granted, the car was only making about 225 whp).

If I stay on my current path my GXL will be receiving an Al flywheel and driveshaft and possibly smaller Al pullies if I can find a good machinist.
