This high-quality R4 curve with a 15° angle per piece lets you accurately model wide arcs and improve race flow. Thanks to compatibility with the main Carrera systems, it easily integrates into your existing layout and expands your building options without compromise.
For perfect stability and appearance, we recommend using the corresponding inner and outer borders. The larger R4 radius supports higher cornering speed, less drift, and smoother driving—ideal for experienced racers and detailed track dioramas.
