any time you remove metal it gets lighter but if rules allow buy an alu. I hope this answered your question

if every thing is under control your not fast enough

Be very careful turning to much material off of a flywheel can be catastrophic.If you have ever seen one come apart,it isnt a very pretty picture.better off trying to find a corvette flywheel.Also,a few thousands arent going to make much difference in weight.

If you decide to do this, make sure you get an explosion proof bell housing. If you go too far and the flywheel comes apart, you'll want to exit the car with both feet in tact.

You need to know WHERE to remove the metal to make it light and strong. Something only an engineer, I suppose, could figure out. Not worth the trouble and the potential for disaster.

go with the z28 and stock clutch. nothing is better than aluminum for response on tacky track but you better push car on trailer or flywheel wont last long!!!! steel lightWeight are too expensive requires special disk and wont last as long as stock. z28 and stock is very light and reliable. nothing worse than having a great handling car but getting smoked on restarts cuz your clutch is slipping!!! or taking home a car and replacing hi dollar flywheel and clutch with what your friends told you to run in the first place!!!!! at least they helped replace it. special thanks BIZUCK AND T-LUCKY.!!!! do your self a favor and you will also be legal 100%

if a flywheel comes apart a blowproof bell housing won't stop it. the bellhousing just keeps clutch parts from coming out if they blow apart.
