I want to get a set of lower springs for my 93 GT convertible...I see alot of used lower springs that will work I think, but most of them are for GT's or coupes...not convertibles whats the difference? Can i use springs form a coupe or hatchback type mustang what will happen if i do? i want the car to be pretty level and sit alot lower then it does now...It sits really high in the rear compared to the front? i have major wheel gap in the rear...its ugly...lol...so what type of lowering springs should i look for or buy? Thanks....
