will 18 alloys from an audi A4 03 plate fit a mk11 vrs

I believe 99% that they are the same 5 x 112 stud pattern.

They are the same stud pattern, but the offset is way off. A4 usually uses ET 35 ish and that will stick the wheels out of the arch. Octavia ET is around ET45-50 IIRC.

doh cheers for that
