The Story
Rear Brake Kit for Mazda MX-5 Miata and Fiat 124 Spider
DFC GEOSPEC Rotors with 5000 Advanced Brake Pads, part number 4502-80101, is a rear disc brake kit built for select Mazda MX-5 Miata and Fiat 124 Spider applications. It combines coated rotors and matched friction material for a service-ready brake replacement on the rear axle.
Key Features
- Rear disc brake kit with DFC GEOSPEC coated rotors and 5000 Advanced brake pads
- Dry-processed rotors arrive ready to install without oil removal
- Silver-gray rotor coating helps resist rust better than conventional paint or zinc coatings
- Rotor machining uses a non-directional finish for more even pad bed-in and smoother stops
- Rotors are manufactured to G3000/G11H18 cast iron specifications and OE-style tolerances
- Brake pads are post-cured, scorched, and fitted with rubber-steel-rubber shims for NVH control
- Part number 4502-80101 for rear brake service on listed vehicles
Product Details
The DFC GEOSPEC Rotors with 5000 Advanced Brake Pads line is built as a complete brake service solution for drivers who want matched rear rotors and pads in one package. The rotor coating is applied to protect against corrosion while remaining safe for the friction surface during break-in. The pads are formulated for stable friction performance, with processing steps that reduce initial bedding time and support consistent pedal feel. This kit is a practical choice for rear brake replacement on the Mazda MX-5 Miata and Fiat 124 Spider, including applications with Brembo-related fitment notes listed below.
This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
What This Brake Kit Helps Address
- Rear brake noise during stopping
- Rust buildup on exposed rotor surfaces
- Uneven pad bedding after brake service
- Brake vibration caused by worn rear rotors
- Reduced stopping performance from worn pads and rotors
Installation Notes
Compatible With rear axle service only. The rotors are shipped dry and ready for installation, which reduces prep time during brake work. Verify the vehicle’s brake configuration against the fitment notes before ordering, especially on 2016-2022 Mazda MX-5 Miata and 2017-2020 Fiat 124 Spider models with Brembo-related brake packages.

Quality Assurance
Each DFC GEOSPEC rotor is machined to tight tolerances, inspected for critical dimensions, and checked for balance on vented designs. The brake pads are post-cured and scorched for stable friction characteristics, then assembled with premium shims for improved noise, vibration, and harshness control. Rotors include a 12-month warranty against defects in material and workmanship.
