Sharpen TRF420 Turn-in with Brass Bumper Posts

Hobbyists tuning a TRF420 will find the Tamiya 54976 Brass Bumper Posts a tidy way to alter front-end feel without bulky ballast. At 6.85g per post, swapping the plastic B5 pieces brings around a 6 gram increase to the nose for a more responsive steering feel.

How the Weight Changes Handling

Placing more mass near the front axle changes the load distribution and can reduce understeer on tight sections. The effect is subtle and suits drivers who want finer steering feedback rather than radical changes.

Quick Fitment Notes

These brass posts are produced for the TRF420 series and fit in place of the original plastic bumpers. The upgrade is a straight replacement job so you can test the setup quickly between practice runs.

These posts add fixed mass at the bumper location. For additional front bias use dedicated front weights or heavier component swaps rather than stacking on the posts themselves.
Brass resists rust but will patina over time. Keep contact surfaces clean and use light oil if storing the car for long periods.
You may need small damping or spring tweaks after adding front mass to maintain balance. Start with minor adjustments and test incrementally.
Yes. The brass posts are a direct replacement and can be swapped back to the original plastic B5 parts at any time.
