Yes, alum. flywheels have a replacement disk.
Yes, any type of flywheel can be torched, blued and heat cracked by any idiot driver like my brother-in-law.
I see some people at a stop light riding the clutch to stay where they are, rather than the BRAKE !
That drives me nuts and I want to slap them !
I am concerned about the lack, of enursha with a light weight alum. flywheel and having to ride the clutch a bit to get going. Some say to release the clutch fairly fast, and you won't have a problem but, what about stop and go traffic ?
