This is true. You can't possibly drive a modern supercar hard enough on public roads, without being arrested/shot, to even come close to troubling the standard 380mm+ steel brake rotors (yes, i'm looking at all you people with Ferraris, Lambos and Porsches who tick the carbon/ceramic option for an extra $20~30k, just to trundle around the city at or below the speed limit)
BUT, big-ups to Nissan for making sure there is an R35 model for that addresses the main concerns for track-heads (the kerb weight and the brake fade resistance of the standard car), and allows the V-spec to compete head to head with cars costing over 3 times as much.
A big part of the reason why the 'Ring lap time is so good- Imagine how many seconds all the lost tenths of a normal gearchange would add up to over the course of 21 kilometres.
