first and foremost, the only reason a person should worry about a "cage" if in one of three circumstances exist...
1) you have built an auto x machine, and you are seriously pushing the rig into corners and think a rollover is a doable feat... wich by the way puts you in a fully modded open class. so since the competition would be fully built miatas and crxs you would really have to push the little thing...
2) you are running 11.5 in the quarter mile and the track ban you till you did so.... but in by doing so you added a hundred pounds and dropped into the 12s defeating the purpose...
3) you messed up and bought the little thing and then realized if an f-150 ran you over, you would die. so your gonna put yourself in a cage to protect yourself from traffic.... if this is the case, thank god you didnt buy a motorcycle....
allthough i do admit if the "hoops" had center beams that went back kinda like the single loop on a shelby cobra has the beam that goes back..
to about where the rear seat back meets the seat bottom...yea that would look awesome....
ill have to crawl out there tomorrow and measure for ya ... heres some pics of it installed...
