The Yokomo B10-202SBLA aluminium steering bell crank is designed to refine steering dynamics on BD10/9 chassis. Its 20mm length from the steering post centre to the linkage pivot is 2.0mm longer than the original part, which alters the Ackermann ratio and increases the outer wheel steering angle for improved cornering capability.
That extra length produces a softer initial steering response compared with stock geometry, yielding a more controlled turn-in that benefits drivers aiming for consistent lap times. The result is smoother handling and easier tuning when trimming steering sensitivity.
