Overview

Enhance the braking performance of your Mercedes A45, CLA45, or GLA45 with Girodisc’s high-performance rear rotor system. This lightweight, two-piece floating rotor assembly is engineered for superior thermal management, reduced unsprung mass, and optimal compatibility with OEM calipers and brake systems.

Key Features

• Direct OEM Replacement
  Installs with no modifications required. Maintains factory brake bias and ABS functionality.

• Aircraft-Grade Aluminum Hat
  Machined from 6061-T6 aluminum for strength, lightness, and thermal isolation from the rotor ring.

• High Carbon Cast-Iron Disc
  In-house manufactured rotor ring with curved vane internal design to optimize airflow and heat dissipation.

• Floating Mount Design
  Uses 10 cadmium-plated steel drive pins, hardened Class 12.9 cap screws, and spring washers to allow axial float and thermal expansion. Reduces rotor stress and minimizes noise.

• Lightweight Performance
  Saves approximately 2 kg (4.4 lbs) per rotor compared to stock, reducing rotational and unsprung weight for sharper response and improved ride quality.
