GiroDisc 2003 Dodge Viper Slotted Front Rotors

The Girodisc system is a direct replacement for the OEM front rotors on 2003 and newer Dodge Vipers equipped with the standard 355mm brake setup. Weighing only 18.4 lbs per rotor, these lightweight 2-piece floating assemblies significantly reduce unsprung and rotational mass, improving acceleration, steering response, and suspension dynamics. This upgrade maintains factory brake bias and ABS functionality while enhancing cooling and fade resistance for high-performance driving. The rotor rings are machined from Girodisc’s proprietary high-carbon iron alloy, cast and processed entirely in-house in Bellingham, Washington. This advanced metallurgy ensures exceptional durability, thermal stability, and consistent braking under extreme conditions. Each rotor features 48 curved directional vanes designed to draw cooling air through the hub like a centrifugal pump, keeping temperatures stable even during heavy track use. Features include: Direct bolt-on replacement for OEM 355mm rotors – no modifications required, Two-piece floating design reduces unsprung and rotational mass, 6061-T6 aluminum hats anodized for long-term corrosion resistance, High-carbon cast iron rotor rings machined to Girodisc specifications, 48 curved vanes improve heat dissipation and braking consistency, Cadmium-plated drive pins with Belleville washers for silent operation, Fully rebuildable – replace iron rings while retaining hats and hardware, Made in the USA from domestically sourced materials.
