This aluminum motor mount base B is sold as a dedicated replacement or upgrade for the Auper D6 chassis line, supplying a stiff mounting surface where the motor secures to the central chassis. The red finish is both cosmetic and functional, helping with consistent motor placement during routine adjustments.
Fit and role: the part is intended to interface with the Auper D6 motor mount area and serves to stabilise the motor location in relation to the spur and pinion gear mesh. A firmer mount helps maintain constant gear engagement and reduces drivetrain movement when the car is under load.
Installation notes: attach the mount using the existing Auper D6 motor mounting holes and matching hardware sized to the original pattern. Verify motor axial and radial alignment during assembly, check pinion-to-spur mesh before final torque, and confirm there is adequate clearance for cabling.
Tuning considerations: fitting an aluminium base can modify heat transfer from the motor and may shift the chassis balance at the rear; consider this item as a tuning lever when fine-tuning gear mesh, motor placement, or body mounting for handling changes.
