Bezerk RC option part for the Yokomo BD8 2017 model. This is a 4.0mm carbon brace to stiffen the rear of the chassis or more precisely move the pivot point of the chassis further forward. It has been designed to clear the motor mount, the spur gear and the rear toe control system. This brace requires the use of the original BD8 motor mount, does not work with the PCS motor mount! This in turn makes the car easier and more consistent to drive whilst providing more steering as well. Like all Bezerk products we can modify the design to suit you needs, thickness etc.
