Got 3000 miles on my 370Z here in Seattle, no problems. Like they said, drive it like you stole it. worked on my sport bikes (R1,R1, R6), seems to be working on the car. Got to love Japanese engineering. I've had 33% tint on my windows, and 3M clear bra on the front, and the Jim Wolf POP charger intakes on my car since February 17 (ordered car Jan. 11, Received Feb 2). Not disappointed with any one of my purchases.
Enjoy your car and maybe I'll see you around. I haven't seen any other 370Z's on the road here in Seattle, but my friends say they have, maybe they say yours.
Got you beat, I was the first in Seattle with tinted windows, and 3M clear bra on the front.
