I don't know why there's so much emphasis on wheelies. I don't think they're a testiment to driving ability. My TMaxx has a .18 CVRX and is capable of pulling wheelies all day, but my truck is set up for racing, and wheelie's just aren't cool on the track.

But ... since you're asking about doing wheelies ... you can also put softer springs on the rear to allow more weight shift to the rear.
