Short XB2 2.0mm thick aluminum chassis is suitable for tracks where more stability is required. Suggested for medium to high traction tracks. The 1-piece chassis design with more flex characteristic generates more overall traction and improves steering. Features extra 4 holes to mount extra stiffener to reduce side to side chassis flex. This help to increase rotation and precision on high speed. CNC-machined from high-quality Swiss 2.0mm 7075 T6 aluminum.
