Girodisc Porsche 350mm Front Rotors

The Girodisc 350mm Front Rotor system is a direct replacement for the factory Porsche rotors, offering a perfect bolt-on fit with no modifications required. Designed to reduce unsprung weight and rotational mass, these rotors enhance braking response, acceleration, and overall performance. Crafted from premium U.S.-sourced materials, this two-piece floating rotor system ensures exceptional strength, cooling, and consistency lap after lap.
Lightweight Two-Piece Design for Precision Braking
The central hat is machined from 6061-T6 aircraft-grade aluminum, anodized for corrosion resistance, and paired with Girodisc’s proprietary cast iron rings poured and finished entirely in the USA. The curved internal vane design acts as a centrifugal pump, drawing cool air through the rotor for superior temperature control during demanding track sessions or spirited driving.
