Really? Does it explain why?
Is that specific to these flywheels, or a standard across the industry? I’ve never had one done myself, my manual vehicles still have their original clutches, but I've known a few who have had flywheels turned, and lightened, but that for a different reason.
read post #16. yes as far as I know it is just on jeeps. I dont have time right now to look it up but look at the manual in the resources section here and it tells you why.
