Hi Iv recently just order at set of AP Coilovers for my A3 Sportback so decided I would also change my wheels. These are the wheels that are currently have fitted and how it sits. Im looking for wheels that have a bit of concave. Heres a photoshop iv done of some A5 alloys that i like. What I understand is the lower the ET the more concave the wheels will be. So I'm wondering whats the lowest I can go in terms of ET without getting any rubbing? Any feedback is welcome.
