    Alloy bell measurements?

    Wondering if anyone can confirm my sizes please? I've got a pair of alcon 4pots and floating 342mm discs and I'm having the bells machined to fit, from info I've found am I correct in saying the hub is 57.1mm where the disc sits? I just need this measurement as I can't get my wheels off till the weekend and need to tell the fella early this week the rest is just bog standard 5x112 and to fit m14 bolts??

    Cheers Graeme

    hat height will be dependent on what bracket you use i would expect and what caliper?

      The disc centre bore is 68mm I think, 57.1mm is the wheel spigot diameter.

        To be honest you need to get this dimension spot on, I'd want to give the machinist an old disc or hub to measure accurately
