The result is a performance brake pad option with a metallic friction material, chamfered edges, slotted pad design, and included wear sensor, shims, brake lubricant, and mounting hardware.
Key Features
- Front disc brake pad set for track day and spec racing use
- Metallic friction material with 13.9 mm inner and outer pad thickness
- Slotted design with chamfered edges for performance braking applications
- Pad shims, brake lubricant, wear sensor, and mounting hardware included

- Performance grade construction for repeated high-temperature braking
Product Details
PowerStop PSA-1903 is part of the Power Stop - Front Advanced Track Day High-Performance Brake Pads line, developed for drivers who want a pad compound matched to specific vehicle platforms rather than a generic street-performance formula. For the Mazda MX-5 Miata and Fiat 124 Spider front axle, this pad set is built to handle the demands of track sessions where brake consistency matters more than low-dust street comfort.
Compatible With 2025 Mazda MX-5 Miata, front; 2019-2021 Mazda MX-5 Miata, front; 2022-2024 Mazda MX-5 Miata, front; 2019-2020 Fiat 124 Spider, front; 2017-2018 Fiat 124 Spider, front; and 2016-2018 Mazda MX-5 Miata, front. This part number, PSA-1903, is a direct fitment-focused option for these front brake applications.
Common Problems This Pad Set Addresses
- Brake fade during repeated track laps
- Inconsistent pedal feel under high braking temperatures
- Premature pad wear in performance driving conditions
- Need for a front pad compound matched to a specific chassis
- Noise and fitment issues from worn or mismatched brake hardware
Installation Notes and Tips
Verify front caliper configuration before ordering, especially on 2016-2018 Mazda MX-5 Miata and 2017-2020 Fiat 124 Spider applications with OE ceramic or 1-piston front calipers. Clean the caliper bracket and rotor surfaces before installation, apply the supplied brake lubricant where appropriate, and follow the vehicle manufacturer’s bedding procedure for performance pads. PSA-1903 includes a mechanical wear sensor and pad shims for the listed applications.
Quality Assurance
