Are there any Roll bars and SFC on the market that are designed to work together to stiffen the car? I was going to get the full Kenny Brown SFC setup (This kit ) and a roll cage. I was wondering if there are any setups that are made to go together. I figured If not, what cage would you guys reccomend? Should i just buy a cage and the SFC's listed above and tie them together with some ttubing? I am i going overkill here?
