i just see this thread now... and now, i think i kinda mess up on my set up,
I'm using the tapered type lugs, and these rays are flat lugs? oh snap,
this whole time, i though the 370z rays are same as the g35 rays (since they use the tapered type lugs)
so i need to change it huh? could that be the reason of vibration... hahahha
btw, here is a pic of my car with the 370z rays
