OK thanks for the advice.
I've already installed braided hoses and have been using Motul 600 fluid. I will need to do something about my current discs as there is some scoring all round. The rears are nearly new, although the fronts are a bit older. How big an issue is scored discs? Is skimming the discs worth considering?
Alternatively, for new discs, MTEC discs are the same price as OEM (http://www.mtecbrakes.com/brake-discs/nissan/370z-coupe-2009/370z-3-7-v6-06-09.html), which would be grooved, dimpled or drilled. Is there any reason not to go for these over OEM?
Thanks
