I have a 2012 mustang gt with the brembo package. I have the stock suspension and I have the chance to buy the full GT500 SVT performance pack suspension. It includes the front struts, front springs, front strut top hats, rear shocks, rear spring, jounce bumpers, front sway bar, rear sway bar (with mounting arms) , pan hard rod, and pan hard brace. The set came off of a2011 gt500 that got converted to a super snaked after only 2k miles. The kit is in perfect shape and the guy wants 600 bucks for it. How much of an improvement would this make to my car and would it improve ride quality or anything? Should I do it? Is it a good price? Help me out guys!! Thanks!
