After I installed a set of springs my rear end was noisy as hell for about 100 miles. After that I got an alignment, didn't help. It would do it when turning at slow/medium speeds and when going over bumps or uneven road. Anyhow, another hundred miles and it shut up. It's fine now.

 

You should be able to "feel" it when you go over bumps There will be a slight clunk sound too. When I say "feel", I mean you can feel the bad shock compressing and rebounding faster than the others. In a car as stiff as the S 2000, its pretty easy to feel this.

 

IT'S NORMAL!

I've had 3 sets of eibachs and they all made the same sound you are talking about. It'll go away after awhile. From what i understand the springs are just settling into the grooves on the top of the strut tower.

 

um... idk.. i think i'm only hearing it from the left, like RIGHT under my feet or near there... so it's gotta be the front left......like slippy said, i get that noise slowing down, turning left, accelrating after going like 5mph, or going over uneven road, the sounding sounds like it hurts the car
