Suspension on the G37
 

My G37 sedan doesn't feel as tight as it used to. Currently has 105,000 miles. Any worn suspension parts that I should look after? Thanks in advance.

Have the dampers ever been replaced? If not, I would certainly look toward replacing them. I'd also take a look over the rest of the suspension specifically looking for worn bushings and feeling for play in the various components (i.e. control arms, ball joints, stabilizer bars, camber arms etc..)
