Verus Engineering Brake Backing Plate Kit with Carbon Ducts - 15-21 WRX/STI

Overview

Improve braking performance and thermal management with the Verus Engineering Brake Cooling Backing Plate Kit for the VA Subaru WRX and STI. Featuring durable stainless steel backing plates and precision-formed dry carbon air ducts, this kit directs cool air into the center of the brake rotors to help manage temperatures during demanding driving conditions.

Designed as the foundation for a custom brake cooling system, the backing plates accept standard 2.5-inch silicone brake duct hoses, allowing fresh ambient air to be directed through the rotors. Improved cooling helps increase brake component longevity, reduce brake fade, and minimize the risk of brake fluid boiling during extended track sessions.

Compatible with OEM and aftermarket big brake kits, the system features stainless steel hardware and hard-anodized aluminum spacers for excellent corrosion resistance and long-term durability.

Brake Cooling Performance

Verus Engineering validated the effectiveness of this brake cooling system through tuft testing and thermal imaging. Testing demonstrated significantly improved rotor cooling, even when used with factory brake rotors, which feature smaller internal cooling vanes than many aftermarket big brake systems.

With the cooling system installed, brake rotors maintained lower temperatures immediately after braking and during subsequent driving without brake application. The system becomes increasingly effective at higher vehicle speeds, as greater frontal air pressure and airflow allow more ambient air to be directed into the center of the rotor.

Track users have also reported several improvements, including:

• Reduced brake fade during extended sessions
• Reduced rotor cracking
• Improved brake pad wear
• Reduced brake fluid boiling
• More consistent braking performance under demanding conditions

By improving airflow through the brake rotors, the Verus Engineering Brake Cooling Backing Plate Kit helps maintain more consistent operating temperatures and supports improved brake component durability during track days and competition driving.
