XRAY 329901-M 12mm Hex Aerodisk Rear Wheels Set  [XR-329901-M]

Engineered Aerodynamics for Precise Handling

Built for competitive track use, the XRAY 329901-M rear aerodisk wheels blend accuracy and toughness. These wheels use a 12mm internal hex so they fit both 2WD and 4WD setups. A countersunk centre recess lets the wheel nut sit lower, improving stability through fast corners.

Built for Tough Racing

Molded from a flexible yet resilient material, the wheels resist impact while holding their profile. The medium hardness gives a sensible tradeoff between traction and lifespan, suitable for a range of racing surfaces. The aerodisk side shape helps cut drag and keeps top speed consistent.

Chassis Stability Features

Internal reinforcement ribs reduce flex and deformation under load, which helps maintain predictable handling during hard runs. That structural support is important for repeatable lap times in close competition.

Bulk Value Pack

This package contains 5 pairs (10 pieces), delivering value by including an extra pair. They are a straightforward upgrade for XB2 and XB4 platforms seeking improved rear-end performance.
