Interesting. Steel gets you moving better, but aluminum recovers between shifts better



Not always. There are ways to make the lighter flywheel combo get you going like a steel wheel.

I don’t argue about it any more because it’s not worth it. I run an aluminum wheel in everything that is going to see some track time.


Of course, if you don’t have a way to APPLY the clutch then the steel wheel is a bandaid to get the car moving. Clutch application is critical.


Can you point us to the thread where you did agrue it ? fan

running up my post count some more .
