This XRAY 354115 brake disk is an RC-scale, extra-large ventilated unit engineered to reduce rotating mass while preserving stable braking behavior during extended runs. The design prioritizes heat evacuation through its ventilated profile and precision-ground contact surfaces to keep braking feel consistent lap after lap.
Compatibility and role: intended for GTX 2026 series applications where a larger, ventilated disk helps manage brake temperatures and braking response. As an RC accessory, it acts as a tuning item to refine brake bite and thermal consistency rather than a primary performance upgrade on its own.
Installation notes: ensure mating hub and rotor faces are clean and free of debris before fitment, verify axial clearance to avoid rotor rubbing, and confirm fastener torque per your chassis manufacturer's recommendations. When replacing existing rotors, check for any required spacer or adapter that matches the GTX 2026 mounting pattern.
Tuning guidance: use this disk to fine-tune braking balance—pair with pads and calipers suited for ventilated rotors, and consider incremental testing under representative run conditions to observe temperature behavior and braking consistency. The reduced rotating mass can slightly change inertia at the driven wheels, so re-evaluate braking modulation in practice laps.
For racers and tuners using GTX 2026 platforms, this XRAY 354115 disk offers a ventilated, precision-ground option to help stabilise braking and improve thermal control during extended runs.
