Hawk HB914W.580 DTC-30 Race Rear Brake Pads 2018-2021 Subaru WRX STI AWD

Vehicle Fitment

• 2018-2021 Subaru WRX STI (2.5L EJ257 Turbocharged Boxer 4, AWD) - Rear, OEM Brembo caliper, FMSI D2118

Fitment Notes

• Rear axle application only - OEM Brembo rear caliper, 0.580 in. pad thickness, FMSI D2118, specific to the 2018-2021 VA-generation WRX STI.
• Does not fit the 2004-2017 Subaru WRX STI - those model years use a different rear caliper and pad shape (HB180W.560). Verify your STI model year before ordering.
• Does not fit the Subaru WRX (non-STI) - the WRX uses a different rear caliper and pad shape.
• For track and race use only - DTC-30 is not recommended for street daily driving without accepting significant noise and dust output.
• Not compatible with carbon ceramic rotors; designed for iron/metal rotors only.
• A mandatory race bed-in procedure is required after installation.

Features

• DTC-30 delivers controllable rear brake torque with smooth, consistent pedal feel and bite - the ideal rear compound for WRX STI autocross and circuit competitors who pair it with DTC-60 on the front for optimized split-friction brake bias.
• Effective from cold - DTC-30's wide operating range starting from 100°F means it provides usable braking performance from the very first stop, unlike higher-temperature race compounds that need a warm-up lap.
• Superior release and torque control characteristics for clean, progressive rear brake modulation - critical on the AWD STI where rear brake bias significantly affects corner entry balance.
• Very wide operating temperature range of 100-1200°F with an optimal window of 100-800°F - covers everything from low-speed autocross use through sustained high-temperature circuit braking.
• Can be run on both axles for maximum rear braking performance, or paired with DTC-60 front for a balanced split-friction setup preferred by many STI autocross and time attack competitors.
• Backed by Hawk's limited lifetime warranty against manufacturing defects.

Product Description

The Hawk HB914W.580 DTC-30 race brake pads are engineered for the OEM Brembo rear caliper of the 2018-2021 Subaru WRX STI - the final years of the VA-generation STI that received a revised rear caliper requiring the FMSI D2118 pad shape. This is a distinct fitment from the 2004-2017 STI rear pad (HB180W.560), and STI owners should verify their model year before ordering. For WRX STI competitors who want the most controllable, temperature-versatile rear race compound available from Hawk, the DTC-30 is the standard choice - widely used on the rear axle of AWD performance cars paired with DTC-60 on the front for a split-friction setup that biases front brake torque for better corner entry.

Unlike higher-temperature DTC compounds that need a warm-up lap to reach full performance, the DTC-30 is effective from cold - making it well suited to autocross where the first run has to count. Its smooth, progressive pedal feel gives the STI driver precise control over rear brake input during trail-braking, an important tool for managing the AWD platform's natural understeer tendency. A proper race bed-in procedure is required after installation.
