Power Stop 13-16 Scion FR-S Rear Z23 Evolution Sport Brake Kit

Drilled, Slotted, and Zinc Plated Rear Brake Upgrade Engineered for the Scion FR-S

The PowerStop K5883 Z23 Evolution Sport rear brake kit delivers a direct bolt-on performance brake upgrade for the 2013-2016 Scion FR-S. The K5883 combines cross-drilled and slotted zinc plated vented rear rotors with Z23 Carbon-Fiber Ceramic brake pads, premium rubberized shims, and a full stainless steel hardware kit into a single 1-Click package that installs on the factory calipers without modification. PowerStop Z23 Evolution Sport pads use a carbon-fiber infused ceramic compound that provides more braking power than standard OE ceramic pads while producing significantly less visible dust, keeping the FR-S rear wheels cleaner between washes. The precision-machined rotors use Tru-Cast technology to hold rotor runout within 0.0015 inch and DTV within 0.005 inch, ensuring the K5883 rotors are balanced and true straight out of the box. The zinc plating on the non-friction rotor surfaces resists rust between brake applications and helps the K5883 maintain a clean appearance behind open-spoked wheels.

Frequently Asked Questions

The PowerStop K5883 is designed for the 2013-2016 Scion FR-S in all trim levels. It installs on the factory rear brake calipers without modification. Always confirm your specific year and trim level against the fitment table before ordering.

The K5883 is validated for the Scion FR-S. The Subaru BRZ and Toyota 86 share the same FA20-based platform and similar rear brake specifications in certain configurations, but PowerStop offers separate part numbers for those applications. Confirm the correct PowerStop part number for your BRZ or 86 year and trim before ordering to ensure the correct rotor dimensions and bolt pattern.

Yes. The PowerStop K5883 is a direct bolt-on kit that uses the factory rear calipers on the 2013-2016 Scion FR-S. No caliper brackets, spacers, or modifications are required. The rotors and pads are manufactured to OE dimensions for direct replacement fitment.

Z23 Evolution Sport is PowerStop's carbon-fiber infused ceramic brake pad compound. The carbon fiber content increases pad bite and thermal capacity compared to standard OE ceramic, providing improved braking response under both street and spirited driving conditions. The ceramic matrix produces fine, light-colored dust that does not adhere to wheel finishes the way metallic pad compounds do, keeping wheel faces cleaner between service intervals.

Yes. All new brake pads and rotors require a bed-in procedure to transfer an even layer of pad material onto the rotor friction surface. For the K5883, perform 8-10 moderate brake applications from approximately 40 mph, allowing the brakes to cool between applications. Avoid hard stops during the first 300 miles of use. Proper bed-in maximizes braking performance and minimizes the risk of rotor warping or uneven pad transfer.

The cross-drilled holes provide escape routes for gas buildup and heat during repeated hard braking, reducing brake fade. The slots sweep the pad surface clean of debris, dust, and glazing to maintain consistent pad-to-rotor contact and friction coefficient. Zinc plating on the non-friction surfaces reduces the surface rust that forms on bare iron rotors between drives, which also helps eliminate initial brake pulsation from rust buildup on the rotor face.

Yes. The K5883 Z23 pads include dual-layer rubberized shims bonded to the backing plate. The rubber layer dampens high-frequency brake vibration that causes squealing, providing near-silent operation under normal street driving conditions. No additional aftermarket shims or anti-squeal sprays are needed for normal street use.

PowerStop covers the K5883 pads and rotors with a 3-year/36,000-mile limited warranty when the pads and rotors are purchased and installed together as a kit. The warranty covers defects in materials and workmanship under normal use conditions. Keep the purchase receipt and any installation records, as they may be required for a warranty claim. Contact PowerStop directly through their customer support channel for warranty service.

Installation Instructions

1. Raise the vehicle and support it on jack stands. Remove the rear wheels.
2. Compress the rear caliper piston back into the bore using a caliper wind-back tool, as FR-S rear calipers use a parking brake mechanism that requires rotation while pressing. Open the brake fluid reservoir cap first to allow displaced fluid to expand.
3. Remove the rear caliper mounting bolts and slide the caliper off the rotor. Hang the caliper with a wire hook to avoid stressing the brake hose.
4. Remove the caliper bracket if required for rotor removal on your specific year.
5. Slide the old rotor off the hub. Clean the hub face of rust and debris with a wire brush and verify the hub is flat and free of buildup.
6. Clean the new K5883 rotor friction surfaces with brake cleaner to remove the protective coating before installation.
7. Slide the new K5883 rotor onto the hub and secure with a lug nut finger-tight to hold it flat during pad and caliper installation.
8. Install the new Z23 brake pads in the caliper bracket using the included stainless hardware. Apply the Hi-Temp lubricant to the pad slide areas on the bracket and to the back of the pad shims only. Do not apply lubricant to friction surfaces.
9. Reinstall the caliper over the new pads and rotor. Torque caliper bolts to the FR-S factory specification.
10. Reinstall the wheels and torque lug nuts to spec. Pump the brake pedal until firm before moving the vehicle. Perform the bed-in procedure before hard use.
