Tune TRF420 Steering with Brass Bumper Posts

Whether testing or race day, the Tamiya 54976 Brass Bumper Posts give TRF420 owners a low-effort way to adjust steering feel. At 6.85g apiece, swapping the plastic B5 parts adds approximately 6 grams to the front, producing a firmer steering reaction.

What to Expect on Corner Entry

Concentrating a small amount of mass at the front helps the car rotate more cleanly into corners and can make steering behaviour more predictable under load. It is a subtle tuning tool rather than a radical change.

Simple Swap Installation

These posts are a purpose-made replacement for the TRF420 bumpers, so installation is as simple as removing the originals and fitting the brass units. No chassis modification is needed for standard fitment.
