what do i need to meet specs wise to be legal? i like the one from kirk racing, only i want to leave out the bar that runs from over the drivers head, down to behind the passengers seat. is that still legal???? i dont want to loose the seat travel. i saw a black one (raceboys i think??) that i liked a while ago. the two bars that go into the hatch area didnt cross, they went straight down. leaving him full visability out his rear window as well. i want that exact same set up, minus the bar i mentioned. but before i order it, i need to know if it will be still be LEGAL, since im going to track the car heavily next season! does anyone understand what im talking about?? thanks!
