Hello everyone I recently lowered my f30 335 with H and R sport springs about 3 months ago and recently I've been noticing that when I go over bumps or even small things on the road I hear a rattle type of noise. I read somewhere online that it's the sway bar end links. I went and tighten them up just in case and they were already tight as possible. The noise is still there and it's really annoying I can go over the smallest bump and it makes this rattling noise in the cabin. Any ideas on what it can be? It's driving me crazy
