Looking to upgrade your rear brakes without blowing your budget? Now you can swap out your stock 271mm discs for larger 302mm rotors while keeping your factory caliper. This simple and cost-effective upgrade boosts braking performance, giving you the confidence you need for everyday driving or spirited runs.

How the Upgrade Works

We’ve sourced upgraded caliper carriers from the Mazda 5, which are designed to fit 302mm discs. By replacing your 271mm caliper carrier with this part, you can install the larger 302mm discs and reuse your existing caliper—no need for a full brake system overhaul!

Benefits of Larger Brake Discs

Why go bigger? Here’s what larger discs bring to the table:

Improved Stopping Power: The bigger the disc, the more leverage it provides to slow your wheels effectively.
Enhanced Heat Dissipation: More surface area helps manage heat during heavy or sustained braking—perfect for long downhill drives or aggressive driving.

Convenient Brake Upgrade Kit

Want to save time? We offer a kit that includes premium 302mm RTS brake discs, so you don’t have to worry about sourcing the parts yourself. It’s everything you need in one easy package!
