flywheel

i was just wondering...if i remove my stock flywheel and "take" mass out of it by drilling holes...not random..of coarse....any problems i could run into?like after installation?...functionallity?...will it crack or warp?......ive noticed that alot of the aftermarket flywheels had some design of holes so i figure i can get away with this and benifit....am i wrong?

yes it'll be bad.

get an aftermarket one dont try to drill yours like that.

it ill prob crack just like crossed drilled disk brakes do. aftermarket flywheels take wheight off where the clucth disk doesnt contact like outer extremeties
