Stability I don't feel any difference, it has spacers installed to even that out. Came that way when we got it. Speed and acceleration compared to mine isn't fair. Stock vs modded but it does do great anywhere, no complaints with the tires at all. The tall tires are the Holeshot xct so they are good tires to begin with. I run the GBC's and couldn't be happier.
