Purpose and tuning use on BD9 RTC rear mount

This aluminum RTC separate suspension mount is intended for the front side of the BD9 rear RTC assembly. It replaces the factory resin suspension mount bushes to provide a firmer, longer-lasting mounting point on the RC chassis.

By replacing the resin bushes the left-to-right suspension pin spacing can be set between 43.5mm and 46.7mm, enabling precise roll center and track width adjustments without swapping suspension pins.

The component is supplied as a direct replacement for the OEM resin bush arrangement on compatible BD9 models and focuses on tuning refinement rather than altering original geometry, delivering improved durability and repeatable spacing under load.

Remark :
Due to limited stock availability, please notice that some Yokomo items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Can I fit this to my BD9 without cutting or drilling?

Yes. It is made to replace the resin bushes on the compatible BD9 variants listed and fits without chassis modification.

Which adjustment range does this mount offer?

The mount permits suspension pin spacing from 43.5mm up to 46.7mm, which is suitable for tuning track width and roll characteristics.

Will this change the suspension geometry?

No. The mount preserves the original geometry while providing a firmer aluminum bush to improve consistency under load.

Why choose aluminum instead of resin bushes?

Aluminum gives greater stiffness and wear resistance compared with resin, helping maintain dimensional stability during extended use.
