Anybody? I just want to know if I can put the GT3 (flat looking) center caps to replace the ugly Comps (bulging looking) center caps... if so, where can I buy a set of 4 GT3 caps?

They are not interchangeable.

in that case, is anything interchangeable or come close? if i can get any flat center cap to fit, i can just stamp the bmw logo on it.

after spending all afternoon looking for a center cap alternative, and ironically, came across this:

So I called up Jim, and they he had them in stock... price was pretty steep, but what's a anal retentive person gonna do... they'll be here next week.

Thanks Jim!
