The XRAY 369911 4WD Rear Wheel Aerodisk is tailored for XB4 chassis and race environments where consistency matters. Made from a flexible yet strong material, these wheels tolerate contact while keeping their shape for repeatable handling.
The aerodynamic side design reduces turbulent airflow around the rear, which helps the car remain composed at high velocity and improves stability through fast corners.
Internal ribs are integrated to minimise deformation under stress, preserving wheel geometry during hard use and extending service life for season-long racing.
Featuring a 14mm internal hex, these wheels mount securely to XB4 rear hubs and simplify installation when swapping or upgrading wheels trackside.
