Best Brake Pads for Subaru WRX: Street, Track and Daily Driver Options

Choosing the right brake pad for a Subaru WRX depends on how the car is used. A daily driver that occasionally sees spirited roads has different needs than a car that runs HPDE events or autocross. Picking the wrong compound means either paying for performance the car never reaches or installing a pad that underperforms in the conditions it regularly encounters. This post covers three brake pad options available for the WRX and which use case each one suits best.

For a broader view of how brake pads fit into a complete brake system upgrade, the WRX brake upgrades hub covers how pads, rotors, and supporting components work together.

What Brake Pad Compound Actually Changes

Brake pad compound determines how the pad behaves across three dimensions: friction level, temperature range, and dust output. A higher friction compound stops the car in a shorter distance but typically produces more dust, more noise, and requires heat to reach its optimal operating range. A lower friction, street-oriented compound is quieter and cleaner but fades faster under sustained heavy use. Neither extreme is universally better. The right compound matches the actual demands of the driving the car sees.

For the 2015 to 2021 WRX with standard steel calipers, all three pads covered in this post are direct fitment options. One important note applies across all of them: WRX models equipped with the Performance Package Brembo calipers require 2004 to 2017 STI fitment brake pads and are not compatible with any of the products below. Confirming caliper type before ordering avoids a return.

Hawk HPS 5.0 Front Brake Pads: The Street Performance Upgrade

The Hawk HPS 5.0 Front Brake Pads use Hawk’s Ferro-Carbon compound, which sits one step above the standard HPS compound in terms of brake torque and fade resistance. For a WRX owner who drives the car hard on the street, runs mountain roads, or wants noticeably better braking than stock without sacrificing drivability, the HPS 5.0 is the right front pad.

The compound delivers shorter stopping distances than OEM pads, consistent pedal feel across a wide temperature range, and low dust output that keeps wheels cleaner than most performance compounds. It can handle light track use such as an HPDE day, but is not designed for sustained race sessions at high temperatures. Cool-down time between sessions is important if the HPS 5.0 sees track use, since extended high-temperature operation pushes the compound past its optimal range.

Fitment covers 2015 to 2021 Subaru WRX with standard steel calipers. The set includes both front pads and ships in 24 to 48 hours at $178.00. A proper bed-in procedure is required after installation.

EBC Redstuff Ceramic Front Brake Pads: The Daily Driver Upgrade

The EBC Redstuff Ceramic Front Brake Pads prioritize a different set of qualities than the Hawk HPS 5.0. The Aramid fiber ceramic compound reduces brake dust by approximately 80 percent compared to OEM pads, produces minimal noise, and includes EBC’s red brake-in surface coating that conditions the rotor during bed-in and allows safe braking immediately after installation.

The Redstuff is not a track pad. Multiple sources confirm it is not suited for sustained race sessions and has a narrower effective temperature range than the Hawk compounds. However, for a WRX that is daily driven and sees spirited street use rather than track days, the Redstuff’s low dust and quiet operation are genuine quality-of-life improvements over OEM pads. Wheels stay noticeably cleaner, brake noise is essentially eliminated, and stopping performance is improved over stock from cold temperatures through normal street driving heat ranges.

Fitment covers 2015 to 2021 Subaru WRX and 2005 to 2014 Legacy GT, with standard steel calipers only. Priced at $211.00 and ships in 24 to 48 hours. Bed-in can take up to 1000 miles due to the hard-wearing ceramic compound.

Hawk HP Plus Rear Brake Pads: The Autocross and Track Day Option

The Hawk HP Plus Rear Brake Pads use a more aggressive Ferro-Carbon compound developed specifically for autocross and Solo II competition. The HP Plus delivers a higher level of brake torque and a wider temperature range than the HPS 5.0, which means it sustains performance through a full track session without the fade that a street-oriented pad begins to show under repeated hard stops.

The tradeoffs are real. The HP Plus produces more brake dust than either the HPS 5.0 or the Redstuff, generates more noise particularly when cold, and performs best once it reaches operating temperature. For a WRX that only sees street driving, these tradeoffs are not worth accepting. For a WRX that regularly attends track days, autocross events, or HPDE sessions, the HP Plus at the rear provides the fade resistance those conditions demand, and the compound can be driven to and from the venue without requiring a pad swap.

Fitment covers 2008 to 2021 Subaru WRX rear, 2013 to 2020 BRZ, 2009 to 2017 Forester, 2013 to 2016 Scion FR-S, and 2017 to 2021 Toyota 86. Priced at $171.00 and ships in 24 to 48 hours. Bed-in is required after installation.

Which Pad Fits Which WRX

For a WRX that primarily sees street driving with occasional spirited use and no track days, the Hawk HPS 5.0 front pad is the most balanced choice. It delivers a meaningful performance improvement over stock while keeping the daily driving experience intact. The EBC Redstuff is the better option if low dust and quiet operation are the priority and track use is not part of the picture at all.

For a WRX that attends track days or autocross events, the Hawk HP Plus rear pad matches the demands of those conditions better than a street-oriented compound. Pairing the HP Plus at the rear with the HPS 5.0 at the front is a common combination for WRX owners who want improved track performance without committing fully to a race compound setup on all four corners.

For owners upgrading both pads and rotors at the same time, the post on DBA T2 slotted rotors for Subaru WRX covers how the rotor choice affects pad performance and which combinations work best. Complete front and rear brake upgrade packages are also available through the brake kits category if sourcing both axles at once is preferred.

A Note on the Brembo Performance Package

All three pads in this post are designed for 2015 to 2021 WRX models with standard steel calipers. The WRX Performance Package includes Brembo calipers that use a different pad fitment, specifically 2004 to 2017 STI fitment pads. This is not a minor detail. Installing steel caliper pads on a Brembo-equipped WRX will result in incorrect fitment and potential brake failure. If there is any uncertainty about which caliper is on the car, confirming before ordering is the right call. The brake pads category at Wrench Masters lists compatible options across both caliper types.
