Yokomo B9-RTCA Rear Toe control system for BD9 2019  [B9-RTCA]

The Yokomo B9-RTCA is a rear toe control system for BD9-series RC touring car chassis that gives tuners an adjustable rear toe characteristic without altering core suspension geometry. It varies the rear toe angle and links toe change to suspension stroke, producing a toe response that reacts as the rear suspension moves.

Use this unit as a setup option when you need a predictable toe progression with compression and rebound. The mechanism is intended as an additional tuning point rather than a replacement for basic alignment adjustments, and can be used to tune mid-corner stability and rear traction behavior within the listed compatible chassis.

Installation notes: the part is designed to interface with the rear suspension area on the stated models. Basic disassembly of the rear suspension and standard hand tools are typically required. Refer to the chassis manual or retailer notes for detailed fitment instructions and any model-specific steps.
