i too have been on the search for hubcentric spacers as well.
i've gotten offers from locasl for 50CDN+!!!!!!

I always hear call tirerack, email tirerack..etc.etc...i emailed "Dameon" or whoever works there but never got a reply. Perhaps cause I got it from a post from 2008?? Lol.

But I really need these spacers too in order for the E39 M5 rims to fit my 89 525i.
