Check these out. When Stinkbug was working on them, there was a video floating around of those on a rodeo and they ropped the front wheel down about a foot with a **** load of force off a ledge right on the slider. Took the impact with out bending and protected the body like it was supposed to. He can probably make a custom set for the VX.
