GR Yaris Small Brake Kit Replacement Disc Set

GR Yaris Small Brake Kit – Replacement Brake Discs (15” Wheel Compatible)

Overview

These replacement brake discs are designed specifically for customers already running our 15” wheel compatible small brake kit on the Toyota GR Yaris.

This product provides a direct replacement solution, allowing you to maintain the performance, fitment, and reliability of your existing setup without replacing the full kit.

The discs retain the same carefully selected dimensions and specification as the original kit, ensuring consistent thermal performance and compatibility within the reduced brake package envelope.

Notes

This product is intended for experienced users and motorsport applications. Installation should be carried out by a qualified workshop familiar with performance brake systems.
