[dave500]

Hi folks, new to this forum so first things first, Hello to all of you.
I am looking to swap the wheels on my wifes 2006 a4 convertible 20tdi.
can anyone tell me what other audi wheels will fit or is it just a4 wheels. she has 18" on at the moment, i would like to stick with 18" may drop to 17" if i find some at a good price.
Any help will be great.
Many thanks Dave

5x112 pcd,audi a4,passat ,mercedes but these will need spigot rings to reduce the centre bore.
