Default Spec Flywheel. Aluminum or Steel - 05-25-2017, 06:42 PM

So I have about 40-45k miles on my Spec Stage 3+ clutch and steel smfw.

I loved that clutch so I went with the Stage 5, since I have Pure turbos now.


My question now is flywheel talk. I have been on the lightweight quest. So i weighed the steel flywheel, and that sucker is 23lbs!

I read the aluminum one is 14lbs. I don't know how accurate that is. But I would assume the aluminum one is lighter.

I really want to know some highway feedback with it. I hear about inertia and stuff. Little bit of laggy-ness off the line, etc.

People who run the aluminum flywheel could you share your experience?

I have the alum flywheel in our white 135i development car. Drives and runs fine, although launching it might be more work.
