I'm really tempted to get the sport-system-plus which is the package you describe with the sportline springs.05GTSILVER said:go to tirerack.com, go to suspension you can get eibach, springs, dampers and sway bars for 878, talk about a deal, wish i would of done this, now i got to get the damper kit and the sway bars sep which = 856, ouch, but oh well. so you see your getting springs for free, pro kit or sportline.
