I was wondering if anyone can help me out with a suspension question for my 2004 S2000. Rear doesn't seem as stiff seems to ride softer than normal. Do I need new shocks? Front end was damaged at dealership and car hasn't driven the same since. Dealership fixed front end and did an alignment because the steering was off center. Rear seems to shimmy when I hit a bump. Had another dealership check it out and they redid the alignment but said the shocks were ok. The tech said that the wear on my tires was feathered. Any idea what the problem might be? Tech visually inspected the shocks but didn't take them off the car.
