The Tamiya 53687 Aluminium Rear Upright is a solid upgrade for racers wanting a more consistent rear end. It is compatible with TB Evolution III, TA-04, TB-02, TRF-414 and TRF-415 chassis and replaces the original plastic uprights with a metal option.
This aluminium upright improves rigidity in the rear suspension, which can translate to steadier lines and crisper turn-in. The extra camber link hole gives more adjustment positions than the factory part, allowing finer balance between grip and tyre wear.
Using the Tamiya 53687 you can alter camber by roughly 1 degree to help maintain a better tyre contact patch. The increased number of link positions and the 1 degree toe option let you refine handling to match track conditions and driving style.
