This rear Z23 Evolution Sport kit answers the weak point of a heavy rear-drive INFINITI sedan or crossover, pairing Carbon-Fiber Ceramic pads with drilled, slotted and zinc plated rear rotors for firmer pedal response and far less dust on the wheel. Beveled drill holes move heat out of the rotor face and rounded slots sweep away gas, debris and moisture so the pad keeps a clean bite through repeated stops. The zinc plating protects the hat and vanes from the surface rust that shows through open factory wheels. Dual-layer rubberized shims control noise, and premium stainless-steel hardware, a pin bushing kit and hi-temp brake lubricant are in the box.
