i have an 09 LT and i wanted to know if any body else with an 09 had switched to sportlines and what was the diff in the ride of the car. also does any body know what the height diff is on the ss springs to the LT springs. i haven't been able to find any upgradable shocks and struts for this car do the exsist? any of you recomend going to ss shocks and struts with a sportline conversion and how siff and bumpy would that make the ride? i just got wheels on the car and since there is like a 4" gap they look tiny. plese help i know nothing about suspension.....
