The Tamiya 42350 Aluminum Lower Deck is aimed at drivers who fine-tune TRF420 setups for high-traction tracks. With its 2mm aluminium thickness and diagonal slit pattern, it aims to deliver stable yet predictable chassis flex.
Matched to the TRF420 architecture, this lower deck improves stability on sticky circuits and the black anodised surface helps protect against track wear. It pairs well with the carbon fibre upper deck Item 42349 to adjust overall torsional stiffness.
