Are these needed for turbo cars?I was thinking of getting a lightweight flywheel, but wasnt sure if they were recommended or not. Thank you for your suggestions.

 

stick to stock or a heavy aftermarket unit. the really light ones have no inertia and rpms drop alot between shifts. Im going to assum by your sig that your trying to make big power therfore a twin disk might be in order and they come with their own flywheels
