It just seems like a lot off effort and price for a stock sized rotor, with a minimal upgrade in braking. I am saying that this would be great if they offered a similar setup for the 350z track or the VR4 setup which would have a much more noticeable increase in performance. IE: a 350z or a vr4 sized rotor with a hub bore of 66.1mm for NISSAN HUBS and a stronger hat would be alot more of an upgrade than a stock sized equivalent. I think most people would much rather put $400 into the 350z brackets and stock track rotors, than to spend $460 for a stock sized upgrade. I thought i was pretty clear nixit, but i apologize if not. I only said this since there are hundreds of people running around with the 350z and vr4 setups already on their cars. A bolt on rotor upgrade for people with these brackets would probably be a good seller.
