When I hit bumps, I keep hearing some scraping noise. Its louder when I go faster as if its the wheel. I don't see anything that could be in the way. I have 19s (G35)on and I'm dropped on Tein S-techs. My last max had the same rims, same drop, and no noises. I changed the struts (Tokico illuminas), thinkin that might be the issue. Nothing. Its worse when ppl r in the back seat as well. Any ideas?

 

Struts are an expensive item to replace when guessing, no? The scraping could be the shield behind the rotor. It may be bent ever so slightly that it takes a bump to make it hit. Another idea that comes to mind is seized caliper. Did you take off the tire and have a look?

When my car had a sound like that I put it in the air, took the tire off, put the lugs on, and recreated the noise while someone was by the spindle watching.

 

Rotor dust shield or siezed caliper

Trimmed the bumper mounting tab in the wheel well?
