I own two cars currently which are 2007 G35S and 2017 GSF.
I use Hawk HPS + steel brake lines on G but GSF is oem pads + lines. I think 80-120 km/h I feel G(Hawk HPS) brake is better. Not sure why? Please be noted that my GSF comes with Brembo big brake. (F:6, R:4)
However Hawk HPS has one drawback. It is not so good below 50 km/h especially when cold. In Taiwan this issue shouldn't be too bad because Taiwan is warm or hot most of time....
One more thing. With Hawk HPS and below 50 km/h, you may need some more foot force when braking...
