well, i got 18 inch rear holeshots on it, and the front end is all stock, cept for the AC bumper..... and i doubt that addds any horses or anything, lol. but i was going to sell my raptor cuz i really hated how it wheelied all the time and i just got sick of it. but now the only time i wheelie is when i want to at low speeds and just thumpo it and pull back and it goes up, but i can holeshot alot better and i beat a modified banshee out of the whole..... thats preaty good.
