For drivers wanting crisper rear response, the Tamiya 53687 Aluminium Rear Upright is a worthwhile swap. It is built for models including TB Evolution III, TA-04, TB-02, TRF-414 and TRF-415 and replaces the weaker plastic upright with a metal alternative.
The aluminium body of the Tamiya 53687 increases rear suspension stiffness and improves handling feel during aggressive driving. The unit also offers three camber link holes rather than the usual two, giving more setup permutations for different track surfaces.
Fitting the Tamiya 53687 allows small camber adjustments up to around 1 degree to help maintain optimal tyre contact. The broader adjustment range supports fine-tuning for grip, balance and tyre life on a variety of surfaces.
