Girodisc Ferrari 355 Challenge Rear Rotors

Transform the braking performance of your Ferrari 355 Challenge with Girodisc’s lightweight two-piece rear rotors. Designed as a direct OEM replacement, these rotors reduce unsprung mass, improve cooling, and deliver smoother, more consistent braking performance lap after lap—without compromising your factory setup.

Vehicle Fitment

Ferrari 355 Challenge
Compatible with OEM calipers and hardware
Direct bolt-on installation – no modifications required

Precision-Built for Performance

The Girodisc system is engineered to replace the factory cast rotors while maintaining factory brake bias and ABS function. Each assembly features a CNC-machined 6061-T6 aluminum hat mated to Girodisc’s proprietary cast-iron rotor ring, both manufactured in the USA. The two-piece floating design allows controlled thermal expansion, reducing distortion and extending rotor and pad life. Internal curved vanes act as centrifugal pumps to draw air through the rotor, ensuring stable temperatures even under repeated heavy braking.
