ah you'll be alright on the inners in the curves,pretty hard to warp a curve! hmmmm! these old trucks are really thick also,pretty hard to warp these girls unless your in the middle of a flat panel holding the blaster in one spot for too long ( five seconds or more) give or take! and it's not the psi that does the warping .It is the heat created from friction, sand meeting metal at a very high speed!well something like that!
