By switching to Girodisc’s lightweight 2-piece floating rotors, you’ll maintain the factory brake balance and ABS function while gaining superior pedal feel, reduced fade, and longer service life.
Race-Ready Engineering for Street and Track
Each Girodisc rotor assembly is fully machined and assembled in-house at Girodisc’s facility in Bellingham, WA. The rotor rings are made from a proprietary high-carbon iron alloy formulated for durability and thermal stability under extreme use. The hats are machined from 6061-T6 aluminum and anodized black for corrosion protection. The 48 curved vanes act as a centrifugal pump, pulling cool air through the rotor to manage heat under high braking loads—perfect for track days or spirited driving.

Features
Direct OEM Replacement: Bolts directly to factory hubs and calipers with no modifications required.
Lightweight Design: Two-piece construction reduces unsprung and rotational mass for better handling and acceleration.
48 Curved Vanes: Directional internal vanes act as cooling pumps to pull air through the rotor for improved heat management.
Floating Mount System: Spring-loaded hardware allows the disc to expand freely under heat, preventing warping and minimizing noise.
Replaceable Rings: The aluminum hat is reusable—only replace the iron rotor rings (part number D1-268) when worn.
Made in the USA: Machined and assembled from premium domestic materials.

Dodge Viper TA, ACR-X Front Rotors
The Girodisc system is a direct replacement for the OE front discs on the Dodge Viper TA and ACR-X. No modifications are necessary—the rotors bolt directly to the car and work seamlessly with factory calipers. By upgrading to these lightweight, high-performance rotors instead of a full big-brake kit, you’ll maintain your OEM brake bias and ABS calibration while dramatically improving braking performance and heat control.
Track-Proven Design, Made in the USA
Each Girodisc rotor is engineered and machined in the United States using premium materials for maximum reliability under the most demanding conditions. The central hat section is CNC-machined from 6061-T6 aircraft-grade aluminum, while the cast-iron rings are poured from Girodisc’s proprietary high-carbon alloy for exceptional durability and thermal stability. With a 48-vane directional cooling design, these rotors act as centrifugal pumps, pulling cool air through the disc to reduce fade and extend pad life.
