Since the doctor let me drive again. I've been putting some miles on the Nismo when the weather will let me. No probems so far. IF THERE IS, I WILL LET YOU KNOW and everybody else. The handling has been a couple of steps above stock. The stock Nismo coilovers now perfrom like they should, because there is no bushing binding going on. For road noise in the car. I can't tell if there is an increase or not because of my exhaust and tires. In all, sounds about the same. Have to wait to spring before I can dial in my rear sway bar.
