I just upgraded to 17" mille miglias - it looked a bit high so I went with Eibach Springs and Billstein shocks. Brought it down about 1.25". Looks much better.
the wheels look pretty close to the wells in the picture but with the new spring / strut combo it never rubs, even on big bumps. The tire size is 235/45-17. I think the billstein struts cost about $400-450 and the springs were close to $200-250. They both have to be removed if you replace either of them so it's best to do them at the same time.
