Yokomo BD10F front balance weights
Yokomo have released this front balance weight to improve traction of the BD10F. The weight can be increased by 40g on each side for a total of 80g, reducing wheel spin that tends to occur during acceleration. This will improve acceleration out of corners and improve your lap times. By using only one screw to fix the weight to the chassis, the effect on chassis rigidity is minimised.
