Yokomo YOKSDMKXW Goodyear Kunnys Mark X Wing Set for On-Road Body  [YOKSDMKXW]

Rear Wing for Precision On-Road Detailing

This is an RC-scale rear wing set designed for on-road body detailing and aerodynamic trimming. The Goodyear Kunnys Mark X Wing Set is intended as an add-on part to improve rear-end aerodynamic behaviour on on-road car bodies used in club and track environments.

Compatibility is scoped to on-road car bodies and body-detailing work rather than a specific chassis; the wing set serves as a tuning element that integrates with standard body mounting approaches used in on-road setups. It does not replace structural components of a chassis and is sold as a body-detail accessory.

Installation is straightforward in typical on-road body workflows, where the wing mounts to the body shell using existing mounting points or common fixing methods for body accessories. Adjusting the wing position and angle lets you evaluate changes in rear downforce and balance during setup sessions without altering suspension or drivetrain parts.

The wing's role in tuning is focused on small, incremental changes to aerodynamic balance: trim or reposition the wing to influence rear grip and high-speed stability, then test on the circuit to confirm handling changes. Treat it as a measured part of the setup process rather than a single-step fix.
