brakes go into the Z. Some things Nissan got away with the bare minimum like our brakes and injectors and other things they over engineered correctly like our engine. They could have done away with the HICAS and put the extra money into brakes . For comparison, Toyota/Lexus doesn't skim on braking in it's sports cars or luxary cars. For example, my Lexus GS weights 3700lbs and the car magazine tests shows it out braking the Ferrari 355 and Porsche Boxter. This morning driving to work showed me how well the car stops on a dime for a 4 door sedan.
