Im trying to get a coilover kit for my 2007 mustang gt/cs and its procharged so it has a little added weight on the front. And ive been looking at the eibach 35101.711 kit which is the correct one for my car which will also fit a 2007 gt500. Eibach also sells 35115.711 which is specifically made for 07-10 gt500. as far as my search the only difference i can find is that they are rated differently the gt is 315lb/in and the gt500 is 400lb/in on the front. Could i buy 35115.711 and install it in my regular gt. since i can also get a better deal on it?
