The new ST-22 rear kit is a fantastic new product for the 350Z/G35 platform. The kit was developed primarily with the owners of the Base, Enthusiast, Performance, or Touring models in mind. All of these models utilize the base rear factory brakes. Many of the owners of these models have purchased our front BBK's, but have consistently complained of rapid rear pad wear, particularly when the vehicle is used on the racetrack. The factory rear brakes use a tiny rear pad and rotor, and they simply do not have the heat capacity to handle track duty.

Up until now, the owner had the option of either 1) constantly replacing the miniscule rear pads as they wore out, or 2) purchasing the StopTech 355mm 4 wheel kit. While the 355mm rear kit has proven to be an effective weapon for combating accelerated pad wear, it is overly large in terms of wheel fitment and weight. The ST-22 is an elegant solution that solves both of these issues.

For the 350Z/G35, the ST-22 is mated with a 328x28mm AeroRotor, which has more than enough heat capacity for anything. It has significantly greater heat capacity than the 350Z/G35 Track Model rear kit, which is 322x22mm, and due to the patented AeroRotor design, it also flows substantially more air. Because of the aluminum hat on the AeroRotor, weight vs. the Track Model rear is over 1 lb. less, despite the larger rotor dimensions. Compared to our existing 355mm rear kit, roughly 6lbs per corner are saved (3 lbs. on the caliper, and another 3 lbs. on the rotor assembly). Heat capacity remains ample however. The pad shape for the ST-22 is identical to that of the rear Track Model caliper, so many street and race frictions are currently available.
