I have an automatic Supra TT 93.5 and my flywheel is missing one tooth. I was looking at prices and for about the same as a stock flywheel I can get an aluminum one that is about 20 lbs lighter. I have heard different opinions on going lighter for drag racing and actually slowing down. Has anyone here with an automatic switched over to one and was it faster? Other people have told me the extra weight of the stock one was better for when it shifts with an auto, it will help it accelerate faster because of the extra momentum the heavier wheel delievers. What do you guys think?
