This is a pretty old thread, but I'm also looking to fit the '86 951 trailing arms under Ghia wings. The trailing arms have the bump stops which as I recall from a Superman thread confirms that they are the narrow arms. What size wheel can I fit, and what offset should I look for (again, under stock Ghia wings).

Thanks a lot.

P.S. Alloy arms are pretty. Is it weird that I what to polish them to a mirror shine and clear coat them like that?
