BD9 Rear Toe Adjuster B9-RTCA for Yokomo  [B9-RTCA]

The Yokomo B9-RTCA lets tuners shape rear toe progression on BD9 chassis to alter grip characteristics as the suspension cycles. It creates a controlled change in toe with suspension travel to help tune rear traction and mid-corner balance.

Consider this unit as an additional tuning option to refine handling trends; it works alongside standard alignment setups to influence how the rear end reacts under compression and rebound. It is not a replacement for base geometry settings but a complementary adjustment point.

Installation notes: the control unit interfaces with the rear suspension assemblies on the compatible models. You will typically need to remove some rear components and use basic hand tools. Refer to the vehicle manual or the seller's fitment notes for detailed steps and any variant-specific considerations.
