I think all these tuners should give up changing wheels. Gangsta Style Escalade wheels don't belong here, you're doing it wrong... I don't care what company, BBS or whatever - they all look bad on this car. Stock wheels are the best ones I have seen, kudos to BMW on making wheels which look good for many years, match the car's looks and performance and are unique.
M6GC wheels was another example of how beautiful stock wheels can be upgraded further.
