the only stuff for the contour as far as ground effects is the svt contour body kit. But, if you're looking for springs and stuff, get em online and get em installed here. I bought my springs at TireRack (HRs) and my Konis through a group buy. Then i went to Carboy to get them installed. My friend with his Cavalier had his suspension installed at Racing Evolution and my friends Accord was done at Hyper Racing.
