Xtreme Racing XO-1 carbon chassis
Xtreme Racing has produced a replacement 3mm thick carbon fiber chassis and top plate for the Traxxas XO-1. Save 16 grams with this replacement, which works with the aerodynamic elements of the original kit part, while keeping a stiffer chassis for more consistent handling over those 100mph+ runs.
