RTC front-side suspension mount for BD9

This aluminum separate suspension mount is designed to mount on the front side of the rear suspension mount when using the RTC option on BD9 chassis. It replaces the resin suspension mount bushes and provides a controlled, machined mounting surface for the suspension pins.

By changing the resin bushes to this aluminum mount the effective left‑to‑right suspension pin spacing can be adjusted, which lets you change rear suspension geometry in small increments to suit track or handling preferences.
