Front sub frame reinforcement
Marty, those bars seemed to 1st show up in the publics eye, a few years ago. A company called XV motorsports got real scientific attempting to improve the suspension of E and B bodies. They had OE quality chassis machines and the whole 9 yards. Those bars were part of thier package, along with a tubular lower core support that tied the front rails together. As for your bars, I would still recommend running a bar straight rather than the curved bar, also run it tighter to the top of the inner fenderwell.
