Girodisc Mitsubishi Evo 6–9 Front Rotors

The Girodisc system is a direct replacement for the factory rotors on Mitsubishi Evolution 6, 7, 8, and 9 models. No modifications are required—the discs bolt directly to the car and work with the OEM calipers perfectly. By upgrading to lightweight, high-performance rotors rather than a full big brake kit, your factory brake bias and ABS efficiency remain intact. The Girodisc front rotors weigh approximately 18.2 lbs each compared to the 22 lbs stock rotors, reducing rotational and unsprung weight for sharper suspension response and quicker acceleration.

High-Performance Construction

The hat section of each rotor is precision-machined from U.S.-sourced 6061-T6 aircraft-grade aluminum for exceptional strength and reduced weight. The rotor rings are cast from Girodisc’s proprietary high-carbon iron alloy, poured and machined entirely in-house in the USA. The curved vane internal design functions like a centrifugal pump, forcing cooling air through the rotor to maximize thermal efficiency during demanding track sessions.
