I am going to install the roll cage bars that will go from the cage inside the car to the front motor plate in the engine bay this weekend. I am going to run the roll cage bars inside the front fenders and bring the bars back into the engine bay after the strut towers (this is going in a 1993 Mustang). I have a $100 dollar 12 ton tubing bender from Harbour Freight. I will have to put a few bends in the bars that came with my Jeggs roll cage kit. My question is this. The tubing bender that I have does not do mandrell bends. It does come with die's for the proper size tubes that puts the inside curve on the tubes. These will not be mandrell bends and I know it will flatten out the tubes a bit. Will this matter when I go to get the car certified? I don't think the car will be faster than 9.50's and I don't need the full 12 point cage. I just want the 12pt cage. Any insight that you guys have on this would be greatly appreciated. Thanks in advance for your experience and knowledge.
