Enhance your track’s handling with inner curbs for Turn 4/15° R4. By widening the inner section of the corner, cars gain more space, reducing the risk of sliding and enabling faster, smoother passes. The set is designed for Carrera Evolution, Digital 132 and Digital 124 slot car systems.
The package includes 12 pieces of inner curbs matching the R4 radius. The curbs are intended for use with Turn 4/15° (20578), to which they fit precisely, maintaining consistent track geometry.
