Are you referring to the 370z Sport package brakes? Those are no longer sourced as Brembos but are now Akebonos in nearly all
Nissan/Infiniti models (except the GT-R):
Akebono Brake Corporation
If you are referring to the Brembo Gran Turismo aftermarket kit then that is overkill unless it's a hardcore track car considering a set of four runs you about $5K.
