Torsional Support for Your F104 Chassis

If you run F104 cars at track days, the Tamiya 4005142 RC Upper Deck is a tidy upgrade to stiffen the chassis. Its purpose is to reduce flex so the car tracks truer through bends and responds more predictably to steering inputs.

Feature Highlights for Track Use

Designed to match the F104 mounting points, this upper deck slots in with minimal fuss. The increased rigidity improves balance and straight-line stability, making it easier to fine tune suspension and steering geometry for faster lap times.

Is any trimming required to fit the deck?

No trimming is normally needed. The Tamiya 4005142 is made to fit standard F104 layouts and uses the original screw locations.

What material is the deck made from?

This part is manufactured to provide a balance of stiffness and durability suitable for competitive on-road use. Treat it like any alloy or composite brace when tuning loads.

Will it affect suspension setup?

Yes. With less chassis flex you may need to soften springs or adjust anti-roll settings to retain grip and avoid oversteer at mid corner.

Can it be used on converted or modded F104s?

It fits most F104-based builds, but heavily modified chassis may require verification of mounting points before fitting.
