I recently bought a 350z with pbm coilovers and when driving over bumpy roads I here this clunking noise coming from the RF area like something is loose. I checked everything and it's all tight. It's sounds like a bad strut top going bad but fairly loud..... If someone had this issue before or any ideas please help me out......

 

I had the same noise 1st left side then right

it turned out to be the BS ichiba front upper control arms bushings failed

I just put on SPL front upper control arms , and all set now

check your control arm bushings

 

Check your front bushings

Thanks for the info when I have a chance imma take another look at the bushing and possible just picking up some SPL lower control arms..... Also could this have happen due to riding so low with stiff suspension? Cause I only have 33k on my car 07' Z

 

Riding low kills the front LCA and compression arm bushing real quick, but it's the cool thing to do.
