I recently installed these on my G37 IPL and have to say they are far, far more compliant than the OEM Bridgestones. I run 33psi front and rear with a square setup, 255's all around. Straight line traction, even with -1.6 degrees camber in back is substantially better. I feel as though I could dial up my dampers a few clicks. I was to the point where I was ready to spend $2K plus on a new limited slip differential.
The noise level is also greatly diminished and seems to be in a different frequency range. I ended up saving four pounds for each front wheel and six for each rear. Even with wider rubber.
I have to recalibrate my brain as the ride says these tires are soft but turn-in is just as good, they stick a bit better in the corners and are even more predictable when they break traction. klj
