Steel or Aluminum?

it's only a slight difference. barely noticable.

however, if you are bracket racing and .1 sec in the 1/4mile matters then by all means go for it.

to be honest, if your rear axle isn't geared properly for racing, you would better spend your money on some 4.10's rather than a flywheel. you would notice a huge difference.

it's a trick item that can tweak a little bit of responsiveness... but nothing like a good setup in the rear or higher compression or aluminum heads or a good double pumper carb. or a narrowed rear with wide slicks. those things will give you a lot more pop.


please dont self-modify a flywheel... get an SFI approved steel or aluminum

drilling holes to remove weight is like asking for a clutch explosion, which can remove your foot.
