Description

GiroDisc A2-032B – Porsche 911 Carrera/C4 (991.1) 350mm

Upgrade the rear braking system on your Porsche 911 Carrera / Carrera 4 (991.1) with compatible 350mm rear brakes with GiroDisc A2-032B. This 350mm rear rotor assembly uses serviceable slotted cast-iron friction rings and lightweight aluminum center hats in a two-piece floating design intended for demanding performance driving.

Vehicle Applications and Fitment

• Porsche 991.1 Carrera
• Porsche 991.1 Carrera 4
• Only the compatible 350mm rear brake configuration

Fitment note: The 350mm dimension refers to the rear rotor. The correct rear pad shape is particularly important for this application; match the existing caliper before selecting pads.

Brake System and Installation

Verify any model-specific installation hardware before purchase.

Two-Piece Floating Construction

GiroDisc combines slotted cast-iron friction rings with aluminum mounting hats and floating drive hardware. This arrangement accommodates heat-related expansion of the friction ring relative to the hat during repeated braking. The system is serviceable: worn friction rings can be replaced separately when compatible replacement rings are available and the hats remain within service limits.

Cooling and Slotted Friction Surface

Internally ventilated friction rings promote airflow through the rotor under rotation. The slotted contact surface is designed to work with suitable performance brake pads during repeated braking events. Proper ducting, pad selection and brake-fluid maintenance remain important for track use.

Brake Pads and Fluid

Confirm the required rear pad profile against the fitted caliper; the front pad shape is not interchangeable. For track use, choose a brake fluid with a suitable boiling-point specification and follow the vehicle and pad manufacturer’s bedding and service guidance.
