Hey guys, looking to lower my 2009 GT 500, and I don't want to do just lowering springs due to making the ride too stiff. What coilovers would you recommend for just a street driven car? Do I really need a 50 way adjustable shock LOL? I found this deal at AM........ Eibach Mustang Pro-Street Coilover Kit 35115.711 (07-14 GT500) ..... just want some opinions before I pull the trigger!!! Thanks!!!
