Setup and function of the BD9 RTC rear mount

Yokomo's B9-RTC-05A is a precision aluminum RTC separate suspension mount B designed for BD9 rear assemblies running RTC. It replaces the resin bushes to offer a firmer, more durable mounting point.

Fitting this mount allows the rear suspension pin spacing to be varied from 43.5mm to 46.7mm, enabling deliberate adjustments to track width and roll behaviour without changing pins.

The part is intended as a direct bush replacement on the compatible BD9 models and preserves original suspension geometry while delivering improved material longevity and consistent 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.

Will this fit as a direct replacement on my BD9?

Yes. It replaces the resin bush setup on the listed BD9 variants and does not require chassis alteration for installation.

What handling changes can I expect after fitting?

Adjusting pin spacing alters track width and roll centre, which will impact corner entry balance and mid-corner stability depending on your setup choices.

Does the alloy mount affect suspension compliance?

The alloy is stiffer than resin, so you will notice reduced flex at the mount and more predictable suspension response under load.

Which chassis numbers are supported by this part?

Compatibility is listed as MRTC-BD919, MRTC-BD919S and MRTC-BD10FF in the specifications.
