big wheels
I've seen many combos that look great, and lots that don't appeal to me. Depends on the car and the overall setup including stance etc.
To me a Duster or Demon does not look right without the rear wheelwell filled up. But I understand those who stay factory, just not for me.
BTW, a friend has a convertable hemi cuda, and made his own set of widened "factory" rallies by cutting up 8 of them, making spacers out of 4, and welding together - looks great. The car is gorgeous in orange/white. I should post a pic.
