With all the crazy and wild cars in the 2013 SEMA show sometimes its refreshing to see a vehicle that doesn’t have any wild paint job or massive blower sticking out of the hood. Instead, clean and understated is the name of the game and this Audi S4 may be the epitome of just that. Having a stock body, the focus for this car is its stance and rather stylish wheels. The real gem is the center lock conversion. That’s right these wheels bolt onto this S4 via a race spec centerlock system. Very cool and also clean. Just the way we enjoy it.
