Just be careful it doesn't weaken the inner ring as could just snap when putting wheels on and off etc.
thanks
@slix hopefully should be done as all the other spacers I've seen are fully flush onthe inside where it fits the job so I don't see any issues arising from shaving a bit of alloy off. It's just like having flat spacers on but with a hubcentric part welded to it.
I'd machine them for you for free, but alas I'm on the other side of the world.
If your lucky you might find some machine shop with some car enthusiast who works there. They might do the job as a homer for a dozen beer. Should take a proficient turner no more than 30 minutes to do all four.
cheers mate, there's a local place to me that has lots of old school machinery and may just be able to help me out so I'll pop around there on Monday and see if they can do this sort of thing.
