****SOLD**** Hey guys, selling my LNIB Ford Racing Boss 302 lowering springs. I only had the rear springs installed for less then 100 miles before i scored a good deal on some coil overs and went that route. The rest of the kit is new. These springs are not be confused with K or P springs, these were designed specifically Boss and Laguna Seca model mustang with adjustable stiffer shocks. They are pricey, but give the perfect even ride height that the K and P model springs dont and is a Ford Racing OEM product for those trying to stay with Ford Racing products only. Give your 2012-2013 Ford Mustang Boss 302 better handing and a more aggressive stance with these Ford Performance lowering springs. These springs lower your Boss approximately 15mm in the front and 35mm in the rear. This kit includes a new Ford Performance jounce bumper to keep your S197 from bottoming out. May cause slightly harsher ride compared to stock springs. Tech Info Lowers Car: Front - 0.6" Rear - 1.375" $260 shipped, I paid $340 for them 4 months ago.
