I feel like a newb asking this but...
My Stang has amlost 50k miles on it. I just got a Centerforce Stage I clutch(disk and plate), and was wondering while that is being done if i would profit from changing the flywheel too.
You need a new flywheel whenever you change the clutch, that would be most Ideal. But you can get it resurfaced and that would do you just as good, and alot cheaper that way. Although I have heard the arguement that you shouldn't resurface flywheels, I did mine when I changed my clutch cause it was like 15 bucks to do as opposed to 400 for a new flywheel, Although I want to get an aluminum one next time. Either way, one or the other should be done to eliminate or reduce clutch chatter.
It's like brakes, when you do brakes you could get new rotors, or have them resurfaced right, which you should do with any brake job.
