Sleeper car , what wheels !!! pics**
I'm not sure if I'd be too concerned with unsprung weight on a "straight line" car. I'd go with any factory offered wheel. The poverty cap look obviously screams basic. I'm not sure if it's the best choice for white, though. The full covers are a bit boring for me, although they would definitely convey the image. Everyone thought my car was a sixer before I put the Rallys and RWL's on.
I also agree with everyone about the scoop. But the twin snorkel just looks so damn cool, and these later cars can really use the extra help in the image department. If they were originally offered on the Duster, I'd use one for sure. Still might, who knows?
