No Brembos for 2005 on 5AT or 6MT.
It was apparent that the braking was the same as a stock system. To improve on the G35 brakes you would probably need bigger rotors, a larger caliper with more pistons, a larger brake pad, and some wider tyres in front and rear.
It is a shame that Nissan does not have a nicer looking, higher quality or a larger caliper for these luxury cars. Brembo, Wilwood, AP Racing, StopTech...have nice brakes that would work. You must upgrade front & rear and may need a proportioning valve.
I would not go to a track event on these brakes. I may try changing the brake pads but expect fade soon. Besides, for the track you want a much lighter car: like my 2,600lb 425rwhp RX-7.
