Brake Cooling

Build a brake cooling system for the demands of track-day driving. Shop APR Performance carbon-fiber brake ducts, rotor backing plates and cooling kits for Subaru BRZ, Scion FR-S, Subaru WRX/STI and Honda S2000 AP2 applications. From front air inlets to the rotor-side connection, find the components to direct cooling air where your brakes need it.

Brake Cooling Kits for Track-Day Heat Management

Repeated hard braking turns vehicle speed into heat. When temperatures exceed a pad’s working range, braking performance can fade. A properly configured brake cooling system channels outside air toward the rotors to help dissipate that heat during a session. It is a practical part of preparing the brakes for sustained circuit use.

Plan cooling alongside the pad compound, rotor specification and brake fluid suited to your driving. Ducting manages airflow; pads and fluid have their own operating limits.

APR Performance Carbon-Fiber Brake Ducts

APR uses shaped inlets to collect incoming air and feed it into the cooling path. High-temperature duct hose connects that inlet to the rotor-side hardware, turning separate components into a directed-air system. Matching those components creates a continuous cooling path from the bumper inlet to the brake assembly.

Pre-preg carbon-fiber construction combines low weight with formed duct shapes. APR’s autoclave manufacturing and UV-resistant clear coat add a distinctive carbon-fiber finish to the functional cooling hardware. Choose the duct for its bumper application and pair it with the appropriate brake-end components.

Cooling Kits, Ducts and Backing Plates

Brake cooling kits are the first place to look when starting a new installation. Compare the application and component package with the system you want to build. A coordinated purchase can simplify planning the inlet-to-rotor air path.

Front brake cooling ducts suit the air-entry portion of the project or replacement of an existing inlet. Rotor backing plates provide the brake-end connection; plate-and-hose packages offer another way to complete or refresh that section. Select individual pieces when you already have part of the system and want to retain the compatible components.

Hose contents depend on the selected package. The standalone BRZ and 2015–2017 WRX/STI duct listings require separately purchased high-temperature hoses. Match the inlet, hose and rotor-side connection before completing the order.

Shop Brake Cooling for BRZ, FR-S, STI and S2000

For the 2013–2016 Subaru BRZ, compare the APR brake rotor cooling kit with separate BRZ ducts and FR-S/BRZ rotor cooling plates. The Honda S2000 AP2 range covers listed 2004–2009 applications. These choices let you start with a kit or focus on the section of an existing system that needs attention.

Subaru options include 2008–2014 STI backing plates and plate-with-hose packages, 2015–2017 STI cooling kits, and 2018–2021 STI kits or ducts. A separate 2015–2017 WRX/STI duct listing serves the front-inlet application. Keep the bumper and brake assembly in view when comparing these choices, especially on cars with aftermarket brakes.

Frequently Asked Questions

How do brake cooling ducts help on a track day?

They feed outside air into a connected cooling system that directs airflow toward the rotors. This helps remove heat generated by repeated braking. The benefit depends on the airflow path and complete brake setup, so choose cooling alongside suitable pads, discs and fluid.

Should I choose a cooling kit or separate ducts and plates?

Start with a kit for a new installation, then compare its contents with the planned system. Choose individual ducts, backing plates or a plate-and-hose package when completing or repairing an existing setup.

Are the hoses supplied with APR front brake ducts?

The standalone BRZ and 2015–2017 WRX/STI duct listings specify separate high-temperature hoses. Other packages have their own contents. Check the selected part number so the order includes the hose and connections needed for the full air path.

Can I use brake cooling with an aftermarket big brake kit?

Check the rotor-side mounting and clearance against the exact brake kit. A larger rotor or different caliper can change the space available for a backing plate and hose. Send your brake-kit reference with the vehicle details for an application review.

Does an APR WRX/STI duct listing mean all STI cooling parts fit a WRX?

No. The front inlet and rotor-side hardware have separate applications. The listed 2008–2014 STI plates exclude non-STI WRX, and the 2015–2017 and 2018–2021 STI kits require their specified STI brake configuration.
