This CNC-machined rear upright is made to work with the Auper D6 on-road chassis as an aftermarket upgrade. It couples the rear hub carrier to suspension links and affects toe and camber responses when the car is loaded.
Finished in red anodize for quick visual checks during setup and during component swaps. The upright is popular when experimenting with different steering and rear-end stiffness settings compared with standard plastic parts.
Fitment tips: confirm bearing and hub bore alignment, check wheel hex clearance, and use the correct torque spec for aluminum mounting screws. Make small incremental setup changes at the upright and test between runs to understand handling effects.
Install this aluminum rear upright when tuning rear-end response or replacing worn components on an Auper D6 on-road car.
