A1-171 Girodisc 2pc Front Brake Rotors

VW / Audi MQB 340mm Front Rotors (Girodisc A1-171) The Girodisc 340mm Front Rotor set for VW and Audi MQB-platform cars delivers a precise, high-performance upgrade over factory rotors without the cost or complexity of a full big brake kit. Each rotor is a direct bolt-on replacement that retains full compatibility with factory calipers and brake bias, while reducing both rotational and unsprung mass for sharper handling and improved acceleration. Precision-Engineered Two-Piece Design Weighing approximately 20.3 lbs each compared to 23.8 lbs for the OEM rotors, this Girodisc system reduces weight exactly where it matters. The central hat is CNC-machined from U.S.-sourced 6061-T6 aircraft-grade aluminum, paired with Girodisc’s proprietary cast iron rotor ring poured and machined entirely in the USA. The rotor’s curved vane internal design acts as a centrifugal pump, forcing cooling air through the rotor to maintain consistent braking under high temperatures. Vehicle Fitment This 340mm G
