I have a Blaster front-end if someone is interested in doing a conversion, full clip, I got it on a trade the other guy tried to put another motor in it, but I checked and it would make a good clip for a Raptor conversion.
if your looking for any type of flat profile tire (holeshot) than your going to have to change rims. the 7" stock rims on the Raptor probably doesn't come in that tire style.
