Dodge Brake Rotors

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.

Specifications Rotor Type: Two-piece floating iron rotor conversionPad Shape: FMSI #1405 (annulus ≤ 66mm)Material: Proprietary cast iron with 6061-T6 aluminum hatHardware: 12 alloy steel drive pins with anti-noise spring washersFitment: Dodge Viper ACR, TA, and GTS with OEM CCM rotorsInstallation: Direct bolt-onSold as: Pair (left and right front rotors) FAQs: Dodge Viper ACR Front Iron Rotor Conversion (Girodisc) Why is a different pad shape required? To maintain ideal mass and temperature control, these rotors use a 66mm swept area. The correct pad shape is FMSI #1405, which Girodisc offers in several compounds. Can I use my stock carbon-ceramic pads? No. The OEM CCM pad annulus is too large for this conversion. Use only the specified FMSI #1405 pad shape. Are these rotors quieter than typical race-style floating rotors? Yes. The floating pins are mounted with anti-noise spring washers that eliminate rattle during street use while maintaining full float under heavy braking. What are the main advantages of switching to iron rotors? Improved thermal durability, easier serviceability, and significantly lower replacement costs compared to carbon-ceramic rotors. Can I reuse the aluminum hats when replacing the rings? Yes. Only the cast iron friction rings need to be replaced once worn, allowing cost-effective maintenance. Ordering Information Sold and priced per pair. Includes left and right Girodisc front iron rotors for Dodge Viper ACR, TA, and GTS models with carbon-ceramic front brakes.
