X1 Composite Rear Wing - 373515-K (High-Downforce) XRAY  [XR-373515-K]

Composite rear wing tuned for 1/10 formula racing

The XRAY 373515-K X1 composite rear wing is crafted to add rear-end downforce on 1/10 formula model platforms. Its aerodynamic contour shifts load toward the rear axle to improve traction and stability in fast sections and on corner exit, without suggesting any full-scale vehicle use.

Approved for ETS competition, this wing is aimed at model-level aerodynamic adjustments where consistent response is required. Raising the wing angle increases rear grip and drag, while lowering the angle reduces both; use this trade-off to correct handling tendencies relative to suspension and tyre setup.

Fit the wing to the X1 series mounting points and check alignment and trim prior to track running. Make incremental angle changes when evaluating setup effects so you can separate aerodynamic impacts from mechanical changes.

For competitors wanting a straightforward increase in rear downforce, this composite wing delivers a stable baseline while remaining eligible for ETS events.
