I have a 02 ws6 m6 ta with the eibach pro kit. It has started to groan and moan and make some noise on some bumps and when I back out of the driveway. Any ideas on what it is and how to fix it. Also I am looking for a pair of sfc's, lower control arms and a new sway bar any ideas on what to get. I want to tighten the car up and make the back grab a little better and not bounce up and down so much
