My personal opinion after “modding” few cars in the past is that it never really "improves" the car in any way. In your case, the 370z already is equipped w/ 14.0-in vented disc; 13.8-in vented disc, ABS; and 19" forged aluminum wheels.
Instead, it'll affect the geometry of the car negatively. Therefore what most of us end up doing is essentially downgrading our cars, especially when it comes to 370z.
Nissan has put millions of dollars & many yrs of RD into the 370z, just like the 350z and therefore it does not need any "modification" from us.
Enjoy the car as it was meant to be enjoyed by genius engineers at Nissan and you will not regret it.
