Sometimes it's better to find out who actually makes the discs/pads
and buy direct, before Nissan add their slice on
This is what I did with my 911, oem parts but not at dealer prices
I know akebono make the calipers but no idea what make the discs
And pads are ??
Iirc R35LEE was breaking a 370z with 2k miles on the clock, I've sent him a link to this thread
IMO the brakes on the 370z are very good and unless you're doing track days or it's cheaper then it's waste of money upgrading
