I recently lowered my 2006 g35x on coupe springs for the rear, and revised z springs in the front. The drop looks sick, couldn't have asked for anything better. I can fit 2 fingers in the rear, and about 2.5 in the front. After i installed them, i have a weird noise coming from the front right side, it isn't a metallic sound, nor is it my tire rubbing anything. The closest noise i can compare it to is what it sounds like when you have a flat tire and the rubber is hitting the road. This noise is the worst when driving under 35 mph, anything over that the noise seems to go away. My initial thought is that it might be the shock, after looking closely it seems like my front left shock was replaced when I got into an accident, the front right looks as if its been there throughout the 70K miles... Has anyone else had a weird rubber sound when they installed new springs? Im going to swap the front shocks and see if it makes the noise then, if it does then im ordering a new shock. There is no visual damage to the tire/spring/shock.. so im assuming it might just be a bad shock.. any advice or suggestions are greatly appreciated.

 

bump.. need some suggestions ..

 

since you are an AWD, I would have a tech inspect the front differential and axles, there is a reason nobody makes lowering suspensions for the AWDs really, the AWD system is a PITA to work with on a lowered car, TONS of issues. If it were as easy as installing coupe springs on it, every company would simply market those to fit the AWD sedan as well but they do not....

you probably have 10 different things that it could be, nobody will be able to tell you 100% on here without properly diagnosing it, don't wait for answers here, take it for inspection asap, you don't want to damage that front diff and be into the car a few more thousand $$$...

 

I'm sure you know Tony that BC makes coilovers for the 'X' now............

 

Whatever happened with this? I am thinking about z springs/shocks for my 05x, but is that not a good idea on the x's?

 

sorry for the real late response, it was a blown shock... heh
