Tamiya 42318 - 1/10 TRF103 Formula Chassis Kit - On-Road Setup Platform  [42318]

Overview of the TRF103 Formula Chassis

The Tamiya 42318 - TRF103 Chassis Kit is a purpose-built 1/10 on-road formula chassis that blends lightweight materials with adjustable geometry. It is aimed at builders who prioritize handling refinement and component flexibility.

Carbon Decks and Structural Benefits

The chassis uses carbon fiber for both upper and lower decks and the front arms to reduce weight while increasing stiffness. Adjustable upper arm mounts enable fine changes to front camber and caster for improved steering balance.

Rear Suspension Options for Track Tuning

Two rear setups are provided: a linked system for maximum traction and a T-bar alternative for smoother behaviour on lower grip surfaces. Switching setups helps tailor handling to the circuit demands.

What Tuners Will Appreciate

The ability to change wheelbase by moving the rear shaft, plus precision aluminum parts such as the servo mounts, make the TRF103 well suited to detailed setup sessions and incremental upgrades.

For builders who enjoy tuning chassis geometry and suspension layout, the TRF103 provides a capable base for competitive on-road performance.
