Hey guys....new to this forum, but just recently acquired a 2007 base GrandPrix w/ 56K+ and looking to lower the car a tad (1.5"frt/1.7"rear). Put 19" Rodericks on w/235.40.19 Conti's and there is still a bit too much gap for my taste. Not looking to slam the car though. Eibach doesn't make a spring set for this model.....any direction?
