Rally Ready M-05Ra Chassis Based on the front wheel drive M-05 chassis, the rally-tuned M-05Ra chassis features a lightweight, narrow, durable, and an easy-assembly semi-monocoque resin frame. The 4-wheel independent double wishbone suspension is equipped with specially designed hub carriers and F/R uprights to increase ground clearance by 5mm. The front skid guard, side guards, and rally block tires are also included to allow you to enjoy both gravel and tarmac driving.
