Schumacher Mi4CXL Worlds suspension mount
From Schumacher, this new modification for the Mi4CXL was developed by their team drivers and used by Chris Grainger to gain an A final place at the 2012 IFMAR World Championships. The modification allows a much more elongated flex to the chassis, allowing it to produce more traction yet maintaining the rigid structure of the wishbone mounting system. Typically lap times will be reduced and the car will have an improved driving feel. Includes chassis mounted steering.
