Tamiya 42279 - 1/10 TRF101W Track-Tuned Chassis Kit  [42279]

A New Chapter for the TRF101 Series

Tamiya extends the TRF101 line with the TRF101W, widening the stance and integrating carbon fibre upgrades. The result is a chassis aimed at improving turn-in and mid-corner stability.

Stiffer Front End with Carbon Arms

The revamped front arms are carbon fibre to boost rigidity and deliver crisper steering. Combined with an aluminium servo stay and updated mount points, the setup gives more direct steering feel.

Chassis Flex Optimised for Track Control

By reducing lower deck thickness to 2.5mm, the TRF101W gains usable flex that helps the car settle on low-adhesion surfaces. Adjusted battery post positions also help shift pitch dynamics to improve front traction.

Smoother Dampers and Faster Response

The middle brace redesign alters pitch damper placement for quicker reactions to surface changes. The new roll damper piston design equalises stroke lengths for more consistent damping across events.

Tamiya TRF101W is aimed at drivers who want a setup-rich formula kit that reacts well to tuning. Its carbon updates and altered geometry make it a practical choice for club and regional racing.
