Rear Bulkhead Stiffener for Auper D6 SAK-D6808B/RE Aluminium Upgrade by 3Racing  [SAK-D6808B/RE]

Rear mount reinforcement panel for Auper D6

This aluminium rear bulkhead cover is supplied as a direct replacement for the Auper D6 chassis. The stiffer panel alters load transfer at the rear of the car, which can change how the chassis responds to setup inputs and driving forces.

Fitting is aimed at experienced model builders and is achieved via the chassis' existing fastener locations. The listing does not state included fixings, so retain and reuse the original screws, confirming alignment before torquing down.

In tuning terms the cover gives two main benefits — it reduces local flex at the rear mount under acceleration and cornering, and it provides a firmer datum for suspension adjustments so small setup changes yield more consistent results on track.

A practical option for Auper D6 racers looking to control rear flex and make suspension tuning more predictable, delivered as a direct-fit aluminium panel.
