Girodisc Dodge Viper (2003+) 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.
Precision Engineering
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.

FAQs for Girodisc A1-006
Do these fit directly on the 2003+ Dodge Viper? Yes. They are designed as a direct bolt-on replacement for the OEM 355mm front rotors—no additional modifications required.
Can I replace just the rings? Yes. The Girodisc rotors are fully rebuildable. Replacement rings (part number GD355.32.52) are available separately.
Will they make noise during normal street use? No. Each rotor assembly uses Belleville washers and spring clips to eliminate rattles while maintaining proper float.
Are they suitable for track days? Absolutely. The Girodisc system offers superior cooling, reduced fade, and better heat management than OEM rotors, making it ideal for both street and competition use.
Enhance your 2003+ Dodge Viper’s braking performance with Girodisc’s lightweight floating front rotors—precision-built for better cooling, faster response, and lasting durability.
