The Tamiya 54938 Brass Adjustable Suspension Mounts are aimed at racers wanting to refine handling through added mass and geometry options. They suit the TRF420, TRF419, TA07 and TB-05 chassis and deliver a heavier feel than aluminium mounts, which can translate to steadier steering in fast corners.
The kit contains three mount styles with varying dimensions so you can adjust leverage and roll response. A sprue of seven bushing pairs provides multiple bore sizes for suspension shafts, giving 25 possible shaft offset settings to test during setup sessions.
These mounts are made for Tamiya TRF420, TRF419, TA07 and TB-05 platforms. Swapping mount positions and bushings lets you dial settings between XD and X placements and fine tune toe and balance to suit circuit demands.
