Mounting and tuning role for BD9 RTC rear suspension

This is an aluminum RTC separate suspension mount designed for the front side of the rear suspension mount when running RTC on BD9. It replaces the standard resin suspension mount bushes to provide a stiffer, more durable mounting point on the RC-scale chassis.

Replacing the resin bushes allows the left-to-right suspension pin spacing to be altered between 43.5mm and 46.7mm, giving a defined adjustment range for roll center and track width fine-tuning without changing the suspension pins themselves.

The part is intended as a direct replacement for the OEM resin bush setup on compatible BD9 variants and serves a tuning role rather than a structural redesign: it preserves original geometry while offering aluminum durability and consistent spacing under load.

Will this mount fit my BD9 without modifying the chassis?

It is designed for BD9 variants listed under compatibility and replaces the resin bushes without chassis modification.

What adjustment does the aluminum mount provide?

Swapping the resin bushes allows suspension pin spacing to be changed from 43.5mm up to 46.7mm for track width and roll behavior tuning.

Is the part intended to change suspension geometry?

The mount preserves original mounting geometry while offering a firmer aluminum bush substitute for tuning and consistency.

What material is used and why does it matter?

The part is aluminum for increased stiffness and wear resistance compared with resin bushings, improving dimensional stability under load.
