Tamiya 84203 - F104X1 1/10 RC Chassis Kit Pro Setup Kit  [84203]

Track-Focused Chassis Tune for F104 Fans

The Tamiya 84203 - F104X1 1/10 RC Chassis Kit is aimed at hobby racers who want a platform that responds to setup changes. With precise engineering based on the F104, the kit gives tighter control when pushing through bends.

Deck and Roll Control

An X-shaped FRP upper deck adjusts roll characteristics to help maintain tyre contact during lane changes. The included aluminum roll damper, finished in black, separates pitch and roll tuning so you can fine-tune behaviour through corners.

Balancing and Reinforcement

A rear axle shaft counterweight with ball bearings enhances rotational balance and rear traction. The chassis also features a carbon-reinforced gear case for increased strength and improved drivetrain feedback compared to standard cases.

Handling and Adjustability

Link-type front suspension combined with a direct drive solid rear axle keeps steering precise and predictable. Adjustable front camber and ride height let you tailor handling to different track surfaces, and the design accepts both Tamiya foam and rubber tyres.

This kit suits racers who like to tweak setups and extract consistent laps from an F104-based chassis, with solid build quality and sensible options for tuning.
