Front-side RTC mounting plate for BD9

This aluminum separate suspension mount installs on the front side of the BD9 rear suspension mount when the RTC option is fitted. It replaces the resin bushings and supplies a machined seating surface for consistent suspension pin location.

Swapping the resin bushes for this aluminum unit lets you change left-to-right pin spacing in measured steps, helping you dial in rear-end geometry for improved balance and feel on different surfaces.

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.

Do I need extra parts to install this mount?

No additional specialised parts are required beyond the standard BD9 RTC hardware. Remove the resin bushes and fit this mount in the front-side position following the chassis assembly order.

Can I adjust spacing without modifying the chassis?

Yes. The mount provides an adjustable range from 39.5mm to 42.7mm so you can fine-tune spacing without drilling or permanent chassis changes.

Will this improve consistency on track?

The machined aluminum surface offers firmer and more consistent pin seating compared with resin, which can help maintain consistent geometry under load.

Is any special checking required after fitting?

After fitting, check suspension pin spacing and alignment, and run small incremental changes to confirm handling before wider setup adjustments.
