Those photos were only to show cool 350Z's color schemes (sorry it was a bit off topic) - without worrying if they are current race cars - I'm impressed with your knowledge of them all.
Are you going to post some details about the race preparation of your 350Z race car?
That would be very interesting to read...what weight are you running?
No problems with the stock front calipers?
Some people say that 2 or 3 o'clock position can cause pad knock off
(I'm slowly preparing my 350Z for production racing)
