Yokomo YZ-2 Brass weights
These 2 brass pieces are designed to improve stability and rear traction on the YZ-2 by adding rear weight. The weight is kept in front of the rear axels to increase stability. If you're running the YZ-2 on lower to medium bite these parts will improve the cars stability and traction. The bigger piece replaces the front rear pivot block and the smaller piece replaces the L brace that goes in front of the motor to secure the motor plate.
