Something to think about though is that they are a heavy rim
I have a buddy with a 350z and he has it modded, maybe 315 to the wheels. I went with him to the canyons because he was invited by a bunch of other Z owners, one guy in particular had a stock Z. My buddy was getting really frustrated because the stock Z was pulling away from him on the take offs. When we hit the bottom my friend asked him what the deal was and he said it's cuz of the rims. XXR's are heavy and this guy had a very light wheel. .I think he said 16 lbs. He then explained to us how rim weight can drastically change the way your car accelerates and brakes.
Anyway, just thought i'd share. But XXR's are nice, i thought of getting these exact ones too, debated on this color or the Chromium Black ones
