This set of outer borders is designed for the 4/15° curve (code 20568) and is ideal for widening the track in fast bends. Thanks to the larger R4 radius, drivers get more space for drifting and more confident cornering without unnecessary collisions.
The package includes 12 border pieces that easily attach to the corresponding sections. The borders are built for long life and precise fit with the 4/15° curve 20578 segment.
