As long as the bends are good and your existing cage is made out of good tube I'd probably just improve it to save a bit of money rather than starting it again from scratch. it shouldn't be hard to put an internal Xbrace in using sandwich plates through the body

haha I doubt it will, you know we like to laugh at those lawn rovers most of the time. Guess you'll be grouped with a lot of the full on comp motors as you have front and rear lockers? when's round one? If you haven't found a bitch I might be up for coming over and running (falling over) around in the mud
