This XRAY 301081 - X4F'24 upper deck is precision cut from 2.0mm graphite to refine steering feel and control during acceleration. The split front profile reduces unwanted binding and enhances front-end bite on grippy surfaces.
Milled screw holes keep installation simple and prevent over-constraining the deck, allowing intended flex where needed. The plate shape is tuned to give a mix of traction and steering neutrality for competitive laps.
When corner sequences demand rapid direction changes, the split deck helps the car turn-in faster and hold a predictable line under throttle.
