Well, on my 2013 GT I recently installed a new Boss 302 brace which I got for dirt cheap at CJs Pony Parts. I also bought several different torque wrenches and socket sets from Harbor Freight for a pittance!! Anyhow, I'll never drive another sports car without the brace. It not only cuts the body roll and dive's when hard cornering, it also smooths out the ride going straight and minimizes bumps and uneven driving surfaces to a degree I would not have imagined had I not experienced it. Being made of tubular aluminum it hardly adds any weight to the front end either. Seriously the best $134 I ever spent on the car. Whichever one you choose will probably work just as good but I give them the highest recommendation I can.
