A1-002 Girodisc Ferrari 348 / F355 Front Rotors

Girodisc Ferrari 348 / F355 Front Rotors The Girodisc system is a direct replacement for the factory front rotors on Ferrari 348 and F355 models. Designed as a high-performance alternative to OEM discs, these 2-piece floating assemblies weigh just 14.3 lbs per rotor—significantly reducing unsprung and rotational mass. This results in sharper handling, quicker suspension response, and improved braking control without affecting factory brake bias or ABS performance. Advanced Construction Each rotor ring is machined from Girodisc’s proprietary high-carbon iron alloy, developed for optimal strength, thermal stability, and durability under extreme conditions. The 30 curved directional vanes act as centrifugal pumps, pulling air through the hub to cool the rotors efficiently during heavy braking. The 6061-T6 aluminum hat is lightweight, anodized for corrosion resistance, and reusable—simply bolt new replacement rings (part number D1-002) when needed. Girodisc A1-002 Features Direct bolt-on
