The Tamiya 54936 Brass Adjustable Suspension Mount (A) is engineered to improve balance and setup versatility for TRF420, TRF419, TA07 and TB-05 chassis. By replacing lighter mounts with brass, you introduce additional weight at the suspension pivot which can help with cornering stability and traction.
The set includes a sprue of seven paired bushings offering varied hole diameters, delivering as many as 25 possible suspension shaft offset positions. These positions allow tuning from XA to C, letting you modify toe angles to match tyres and track demands.
This mount is a straightforward upgrade for users of the TRF420, TRF419, TA07 and TB-05 platforms. Its extra mass can smooth chassis reactions and boost grip, which is useful in faster sections or on surfaces needing more bite.
