I never leave reviews on anything and live off Amazon. I bought these for my 08 G37S so my new wheels can clean my calipers. I installed them after thoroughly cleaning the hub and using Loctite. There was cab and steering wheel vibration of about 55 mph+. So I balanced my new wheels 3 times and quit road balancing. I can't solve the problem with vibration. So I ordered a pair of Ichiba spacers for $140. I no longer have vibrations. It just shows that you get what you pay for. If you value your car and want a smooth ride, DO NOT BUY THIS! PAY $100+ FOR RIGHTS!
