    It will vary a lot depending on how hot it gets and how much it gets hot. I have seen a lot more than that and in fewer miles. .

    Interesting. I'll be going with the Hill Engineering Flywheel when I do my clutch in the next month or so.

    I have never needed to replace one. I know a lot of shops who had so much trouble getting them surfaced correctly they replace them. I bought a few of those so I had some spares sitting on the shelf surfaced and ready to install.

    Tell me I'm wrong , but that surface has been machined in a lathe . Should it not have been ground ?

    I agree. Lathes do not cut hot spotted surfaces well at all. I'd never install that.

    A good clutch place will have the proper grinding machine.

    Did the stone turn/rotate ? You then get a circular cut while the flywheel is also turning .

    Um, the cup wheel stone is meant to spin, fast.
