Like probably alot of you on here lowering your car is something you debated over and over. I have lowered everything I have owned and the 300c was the same. I debated which spring and finally went with the Ground Force. I like the fact that they are 1.3 front and 1.6 rear to get rid of the rake a little. I am extremely pleased with them in every way, rides very close to factory with a smooth, and not at all harsh ride. The best part is the stance, gap is the same all around and looks lower than a 1.6 Prokit that lives around me, I love them and for the extra 70 bucks over the prokit, well worth it. Just thought I would post this because I tried to find someone to ask questions before I bought and found no one. Will post pics in a couple of days.
