Ever since I went from 16 inch wheels to 17 I noticed that my z is not handling as well. Because of the bigger wheels and new tires vs the smaller wheels and bald tires my ride height went up 1 inch. My friend has 97 ws6 and he put eibach springs on his car and has his stock springs just sitting there. Would be benefical for me to swamp springs, his car did handle better then mine with his stock springs but I am pretty sure its not just because of his springs, or is it?
