There are multiple brake caliper combinations for the 2003 WRX model year. The only way to ensure you are buying the right pads for your car is to measure the pads already on the car and use the picture on the left as a guideline.

The pads on this page are for 2002-2003 WRXs with the same pad dimensions as the image to the left (D721 front and D770 rear pads).

Posi Quiet pads are a great budget minded replacement because they manufactured using the same positive molding process utilized by OEM manufacturers. This process assures consistent friction material density throughout the pad, resulting in even wear and performance characteristics throughout the life of the brake pad. Posi Quiet pads feature precision cut backing plates and mechanically attached shims, small details that ensure proper fitment in the caliper and virtually eliminate noise associated with pad vibration.

An additional scorching process forces any impurities out of the friction material and pre-burnishes the pads to speed up the pad break-in process.

StopTech now offers the same pads that they include with their balanced big brake upgrades as OEM replacement pads for your stock calipers. StopTech Performance pads are a great option for those that are looking for a good all around street pad that may see limited track time. Designed with a higher heat tolerance and temperature range, the StopTech Performance pads will out perform most other OEM quality pads on the street or track.

StopTech Performance pads will show less pad deposition and lower levels of dust and noise when compared to the popular Axxis Ultimate brake pads at the cost of slightly less initial bite. StopTech Performance pads are designed to be used on the street with very limited track use.

Hawk Performance Ceramic brake pads were developed for those enthusiasts who want to improve stopping power without the annoying side effects sometimes associated with more aggressive pads. Hawk Performance Ceramic pads are engineered with a linear friction profile for maximum performance while reducing NVH (noise, vibration, and harshness) for a smoother ride and ultra-low brake dust accumulation. In addition, you can expect Hawk ceramic brake pads to provide increased pad and rotor life and a more responsive ABS braking system. Hawk Performance Ceramic pads are intended for street use only

Hawk HPS (High Performance Street) pads offer a tremendous improvement in braking distance over the Subaru's OEM pads. Hawk's unique Ferro-Carbon formula was developed for street performance using the safety and quality of Aerospace and Motorsports severe-duty friction technology. The HPS compound offers a high coefficient of friction and can provide you 20-40% more stopping power and improved resistance to fading over Subarus's OEM replacement pads. HPS's Ferro-Carbon compound provides your Subaru with increased stopping power, long-life, less dust and reduced noise compared to other after market performance brake pads. All Hawk Performance products provide a limited lifetime warranty, ensuring products to be free of defects from manufacturer's workmanship and materials. Hawk HPS pads are designed primarily for a daily driven Subaru but will hold up under light autocross duty as well.

Hawk HP+ pads are made for the Subaru that gets driven to and on the track. The HP+ offers increased friction over the HPS, at the price of a little more noise (squealing) and more dust. Brake squeal is not uncommon in the HP+ due to the higher temperatures required for their peak friction, but once warmed up, this higher operating temperature will consistently allow your Subaru to brake more quickly, with minimal fade. These pads are excellent for the occasional HPDE/track day or for the very competitive autocross driver.
