Before I was thinking it was imperfections in the tires...but been there done that. Could it be the stock shocks?? Maybe I need new shocks . I know that my car can be smooth even with after market wheels...so whats going on??

I'm thinking of taking it in for a diagnostic and figure out what could be causing the rattling. It happens around mid range speed ( 50 to 65 mph). Before I was thinking it could just be the roads,...but nah i know my car.

Anyone else have or had this issue? Thx everyone!

it could be so many thing. But ost likely your tire/s. What tire you got on and what was the last time you changed it rotated it and how much thread left on them?

Did you hit any curb?

I had this issue with brand new tires i bought before these one's just 2 weeks ago. So decided to go in and get these hankooks S1z. So i narrowed it down, its def. not the tires. Ive never curbed my wheels or tires. The tires are less than 2 weeks old.

Your issue is this:

Eibach Pro Kit/Camber kit

Lowering your car will make it develop rattles

I disagree, it was fine lowered with my other g37 wheels and tires, not a single shimmy or rattle what so ever. It could be the balancing...those cheap *** weights they use at America's tires keep falling off!!

Thanks for your input Chris, much appreciated
