The XB4 platform works at the highest competition level in any track conditions, whether it be super-low-traction dusty tracks, medium-traction, or super-high-traction carpet or astro turf; there is an XB4 for you that will handle flawlessly in any of these conditions.

There are two different XB4 kits to choose from – Carpet Edition and Dirt Edition, both built on the same platform with full compatibility with interchangeable parts.

The Carpet Edition is designed for medium to very-high traction conditions, while the Dirt Edition is designed for very-low to medium traction conditions.

The Uni-Platform™ allows either version of the XB4 to be tuned or converted to suit any track conditions with only a few additional parts.
