...some new wheels. I've narrowed it down to two light weights!
Oz Aallegerita 18x8 ET48

BBS CH-R 18x8.5 ET48 (?) (will need 3mm spacers to clear brakes)

I've done a few photoshops to help visualise them in the car:
Matt Black Oz Allegerita

Titanium Tech Oz Allegerita

Satin Black BBS CH-R with SS Rim Protector

Satin Black BBS CH-R without the rim protector (not sure if possible)

Current Wheels

My front brakes are AP Racing CP5570.
Let me know your thoughts...
