The XT8 chassis ended up being redesigned to fit both SOFT and HARD composite radio containers without chassis modification. The SMOOTH radio package produces increased traction since it enables the framework flex many is recommended for many standard track conditions. The ROUGH radio package increases vehicle stability and it is recommended for quite high heat and high traction conditions. Leading and back downstop screw areas were redesigned and repositioned for improved suspension down travel and increased reliability. The motor was relocated more rearwards. The framework is CNC-machined from 3mm high-quality Swiss 7075 T6 aluminum; strategically machined in low-stress areas and anodized to make it as light as possible without impacting strength or rigidity.
