Mercedes 402mm Front Iron Rotor Conversion
Girodisc’s 402mm front iron rotor conversion gives your Mercedes the braking consistency and durability that carbon-ceramic rotors simply can’t match. This direct bolt-on upgrade replaces the OEM carbon-ceramic setup with a lighter, more serviceable, and thermally stable iron rotor system—ideal for high-performance street driving and demanding track conditions alike.
Performance and Precision in Every Detail
Each Girodisc rotor is meticulously engineered in the USA to handle the extreme heat cycles that come with repeated high-speed stops. The 6061-T6 aluminum hat is CNC-machined for perfect fitment and anodized for corrosion protection. The proprietary high-carbon iron rotor rings use a curved vane design that acts like a centrifugal pump, channeling cooling air through the disc to minimize heat soak and brake fade. The result is a system that’s lighter, cooler, and far more predictable than OEM carbon-ceramic rotors.

FAQs – Mercedes 402mm Front Iron Rotor Conversion
Why convert from carbon-ceramic to iron rotors? Iron rotors handle heat cycling better for repeated heavy braking and cost significantly less to maintain.
Do these work with my factory calipers? Yes, they’re designed to bolt directly to the OEM AMG 6-piston calipers without modification.
Will they increase brake dust or noise? No—Girodisc’s anti-noise washers and precise fitment keep the system quiet and refined for street use.
Are they suitable for track driving? Absolutely. These rotors are built to withstand the extreme heat of track sessions while maintaining smooth, fade-free performance.
Upgrade your AMG’s braking system with Girodisc’s 402mm front iron rotor conversion. Experience cooler operation, improved control, and long-lasting reliability—engineered for the performance and precision your Mercedes deserves.
