About the XB-F1 Kit

Advanced Race-Bred Front Geometry Design

The XB-F1 uses 1/8-inspired front steering knuckles with zero axle trail, allowing quick camber and track width adjustments for sharper turn-in, reduced cornering resistance, and faster, more linear steering.

Maximum Setup Adjustability & Tunability

Multiple roll center, camber gain, caster (0°–3°), rear pivot, battery position, and spoiler adjustments give drivers precise control to fine-tune balance, grip, and response for any track or driving style.

Refined Drivetrain Performance

A redesigned 3-point ball differential eliminates common wheel alignment issues, delivering smooth, consistent power transfer, improved reliability, and easier maintenance during race weekends.
