The XRAY 329901-Y aerodisk rear wheels are specified for both 2WD and 4WD RC vehicles, giving drivers a durable wheel option for circuit work. They fit a 12mm hex mounting system, making them compatible with many popular chassis, and the hard compound build is aimed at riders who prioritise longevity over extra tack.
These aerodisks use a firmer material to reduce wear and keep handling predictable during aggressive cornering. The 12mm hex connection provides a tight, slip-free interface to the axle which helps maintain consistent traction through long runs.
For racers switching between vehicle types, the XRAY 329901-Y wheels provide a flexible rear-wheel choice that works on both 2WD and 4WD setups. Their yellow finish makes it easy to spot the hard compound option when preparing multiple cars.
