Official pictures of the the new Tamiya aluminium rear uprights are available from Tamiya. It might seem like a strange option for anyone that runs a Tamiya that has rear toe blocks as you can set the Toe-in with those so why would you need these?
The main difference is that you can reduce arm sweep at the rear which changes the behaviour of the arms movement through the corner. Arm sweep makes the suspension bind, the larger the angle the hinge pin, the more bind you will find forces working against each other as it starts compressing.
Using these will give you more linear bind free movement. It also lets you be able to make the rear end more narrow, and allow potential longer arms etc to be mounted.

42341 TRF419 Aluminum Rear Uprights (2°)
Aluminum rear upright set to 2 degrees of toe-in. By applying a toe angle on the upright, it does not take too much traction on the rear during cornering, achieving a light footwork. It is made of aluminum, has high rigidity, and enables stable cornering with less deflection even at high speed cornering. It also supports TRF 418 suspension and 53928 short reversible suspension arms.
