The Tamiya 42342 Aluminum Rear Uprights are a practical upgrade for TRF419 chassis owners wanting keener control. The built-in 3 degree toe-in helps the rear track more predictably when pushing into corners.
Made with touring car performance in mind, these uprights influence traction during turn-in and mid-corner phases. Drivers will notice steadier rear grip when increasing corner speed.
Forged from aluminium, the uprights are more resistant to wear than molded components and help keep unsprung weight manageable for improved suspension reaction on varied surfaces.
These uprights slot into the TRF419 mounting points with minimal fuss, so you can fit them roadside and get back to fine tuning your setup without prolonged downtime.
