Goosebumps are really tall in the middle. I think with most of the bodies I have run you get a little rubbing in the front and some in the back on landings. It might be more of a killer for 2w because it can slow that tire some but with 4w you have drive to the front wheels anyway. I run my body pretty low and it does rub at times in the high speed sweepers but it does not seem to slow me down or effect handling that I notice. The truck is faster through those section because the body is low and aerodynamics at those speeds, but every truck and driving style is different.
