MR-4TC Drift Anti-Roll Wire - Yokomo SD-412  [SD-412]

Durability and Care for MR-4TC Anti-Roll Wire

The Yokomo SD-412 Anti-Roll Bar Wire is an RC-scale anti-roll element specified for use with the MR-4TC series chassis, intended for drift suspension setups. It is a wire-form bar designed to influence lateral roll behaviour, giving a straightforward way to adjust how the chassis responds during cornering and sliding.

This part's role in setup is purely mechanical: by changing the wire's effective stiffness or swapping to a different wire profile, you alter roll transfer between the left and right sides of the car. That change affects weight transfer, entry rotation, and mid-corner balance on a drift car without altering dampers or springs.

Installation is direct and normally uses the same anti-roll bar mounts on MR-4TC layouts. Check alignment and mounting points on your chassis before fitting, confirm the bar moves freely through its travel, and verify there is no binding with suspension links or bodywork. Small incremental changes to wire length or mounting radius deliver predictable tuning steps.

For maintenance, inspect the wire for bends or deformation after impacts and replace if the wire no longer returns to its intended shape, as a deformed wire will change handling characteristics.
