This is an optional XRAY 2.0mm Graphite Chassis, and is intended for use with the XRAY T3 2012 1/10 touring car. This 2mm chassis was developed to provide the best possible traction for low-traction conditions. The thinner chassis allows the car to flex more, generating more overall traction than the stock 2.5mm chassis.
NOTE: When changing the chassis, the roll centers will be 0.5mm lower compared to the standard chassis. Therefore, to keep the same roll center height you need to use 0.5mm shims under all lower suspension blocks.
