Tamiya 42289 TRF102 1/10 Formula Chassis for Competitive Racers  [42289]

Engineered TRF102 chassis for consistent lap performance

The Tamiya 42289 - 1/10 RC TRF102 Chassis Kit is engineered for 2WD formula racing where consistent handling and setup flexibility matter. Its T-bar-type rear suspension separates pitch from roll motion, helping maintain tyre contact across varying track textures and supporting focused race setups at events like the Tamiya Grand Prix.

Stiffness control with twin carbon decks

The design pairs a 2.0mm carbon upper deck with a 2.5mm carbon lower deck to deliver controllable stiffness and bend characteristics. Combined with a floating traction battery mount, the arrangement helps centralise mass and improve turn-in stability.

Independent rear action and accurate steering

The T-bar system allows independent control of roll and pitch, while the low roll point increases roll moment for improved cornering balance. The pitching shaft is self-contained for smooth behaviour over bumps, and the aluminium servo mount plus carbon steel bridge provide a robust steering platform.

Expanded mounting area and fine-tune options

Compared with the TRF101, the TRF102 supplies more mechanical mounting space so you can position electronics for optimal weight distribution. The adjustable aluminium motor mount also lets you refine rear wing angle and drivetrain alignment to suit different circuits.

The Tamiya 42289 - 1/10 RC TRF102 Chassis Kit is aimed at experienced hobbyists and racers who want a chassis that responds predictably to setup changes and delivers repeatable results.
