Tamiya 54976 TRF420 Brass Bumper Posts Front Weight Upgrade OP-1976  [54976]

Dial-in Steering for TRF420 with Brass Posts

For drivers wanting cleaner steering on their TRF420 chassis, the Tamiya 54976 Brass Bumper Posts provide a simple upgrade path without adding bulky weights. Each post weighs 6.85g and replacing the plastic B5 parts adds roughly 6 grams to the front, sharpening steering response where you need it most.

Benefits on Track

These brass bumper posts shift a small amount of mass to the front axle, which can improve front grip and turn-in precision. The change is subtle but effective for setups that need a touch more front-end sensitivity on technical circuits.

Fitment and Swap Notes

Made for the TRF420 lineup, the brass posts are a direct swap for the factory plastic posts. Installation is straightforward: remove the stock B5 components and fit the brass items for an immediate change in steering behaviour.
