big wheels
IMO i think any size can look good i just think it depends on how you go about your build a real custom look, looks good with bigger rims, but an old school hot rod/drag car look look good with 15's and such. i have a 2 wheel drive 68 d100 big block truck that i plan on using as a driver and i want something like 17 or 18s maybe bigger on the back and 16 or 17s on the front and on my future racecar 15s or maybe 16s but hey that's just my 2 cents
