XRay Super-Lightweight Ventilated Brake Disk XR354115

The XRay Super-Lightweight Ventilated Brake Disk - Precision-Ground - X-Large, part number XR354115, is an extra-large ventilated brake disk for racing applications. Its ventilated design is intended to support heat dissipation during extreme racing conditions, helping the braking system manage heat over long runs and demanding finals. Precision-ground construction is specified to improve braking consistency, while the lightweight build reduces rotating mass. These features are described together to provide stable braking performance when the brake disk is used in racing conditions. The extra-large format identifies this as the X-Large version of the brake disk range. Its specification combines ventilation, precision-ground finishing and low weight in one component for use during extended racing sessions. The design addresses both heat management and rotating mass, while the precision-ground surface supports the stated aim of maintaining braking consistency across long runs and finals under demanding conditions.
