This is an RC-scale front balance weight designed for use with Yokomo BD7 and BD5W on-road chassis layouts. The part mounts at the front of the chassis to alter mass distribution ahead of the front axle, helping to fine-tune steering response and entry grip without changing suspension geometry.
The kit includes 2 pcs, one for the left side and one for the right side, each weighing 15g as specified by the original source. The pair is intended to be fixed to the designated front mounting points on BD5 world spec and BD7 front assemblies; verify fit and clearance before final tightening to avoid interference with steering linkages or shock components.
Use this balance weight when you need small incremental changes to understeer/oversteer balance or to stabilize the car's front-end during corner entry. Install symmetrically for overall front bias, or swap/remove one side temporarily during setup checks to evaluate handling differences.
