Tamiya 42279 - 1/10 TRF101W Wide-Tread Formula Chassis Kit  [42279]

TRF101 Heritage Refined Into the TRF101W

In formula on-road racing circles, Tamiya keeps pushing design boundaries. The TRF101W advances the original TRF101 concept with a wider tread and targeted upgrades to sharpen lap-to-lap consistency and corner precision.

Front Suspension Upgrades for Sharper Steering

The TRF101W fits rebuilt front suspension arms made from strong carbon fiber to improve feedback and steering feel. A reworked aluminum servo stay and a new front suspension mount help the chassis respond more directly to steering inputs.

Balanced Flex for Better Low-Grip Performance

Reducing the lower deck thickness to 2.5mm increases controlled flex, which helps manage traction on lower-grip surfaces. Repositioned battery posts also alter pitch load to boost front-end contact and predictability.

Damper Revisions for Quicker Response

A new middle brace changes how the pitch damper connects, producing faster reaction to bumps and transitions. The revised roll damper piston keeps contraction and extension travel consistent for smoother handling through sequences.

The Tamiya TRF101W is aimed at drivers who demand fine control and setup flexibility. Its mix of carbon components and revised geometry makes it a strong choice for those refining race setup and technique.
