I like the mods you have so far. Good choice on the rims
I would recommend:
Visual:
- Match paint side moldings
- ZKW Angel Eyes (from germanStuff4you.com)
- AC Schnitzer Eyebrows
Performance:
- Cold Air Intake
- Performance Chip
- Shocks and Springs ( I put in Koni shocks with Eibach springs, which I think works well, but there are other setups)
- Upper strut brace
- Underdrive Pulleys
