my parents decided to give me money to buy a roll cage for my birthday. I think i'm gonna go with rockstomper, everyone seems to be pretty happy with them. my question is, would it be a good idea to have the cage run across the floor as well for the seats to mount to, or is that unnessary? would rockstomper even do that for me? Also, the standard 1.5" tubing they use should be enough, right? Any other options I should get with this? Thanks for the help.
