Does anyone know which space saver wheel I will need for my Z4 3.0si coupe on 18" Star Spokes? I was under the impression the 125x80xR17 from the e46 would fit, but I have been reading some conflicting info that says maybe the offset of this will be wrong and it will bind to the brakes and that I need one that sits farther off eg the one from an e90? Anyone have any info or actually tried fitting one?
Cheers,
Al.
