I have a 2001 gt with eibach pro kit springs on it.i put this kit on shortly after i bought the car in 01 ,but lately i been noticing i'm bottoming out on dips and bumps seem harsh.I also noticed the pipe from the exaust seems to be rubbing the axle.I'm thinking its the shocks went bad .Whats the BEST shock used with the eibach pro kit?I like to get bilseins but im not sure they are compatible with these springs.Can anyone help?
