R1 Wurks adds another setup option to its R1B buggy with an optional chassis shortened by 4mm. Listed under part number 920290, the plate follows the now familiar short-chassis principle, an option that is increasingly common in 1:10 2WD.

A -4mm chassis that moves weight forward

The principle is simple: by cutting 4mm from the rear section of the chassis, R1 Wurks moves the weight distribution forward by the same amount and shortens the wheelbase. The stated result is a more nimble car that rotates earlier and more decisively on corner entry.

Which tracks is it for?

This configuration suits layouts that string together quick direction changes and drivers looking for aggressive handling, where the standard chassis remains more settled through long sweepers and on fast tracks. It is typically a setup option to swap depending on the race weekend rather than a permanent replacement.

Construction and compatibility

The plate is machined from high-strength 7075-T6 aluminium and finished with a durable black hard anodised coating. One thing to check before ordering: some rear battery positions are no longer available with this chassis, and compatibility depends on the electronics form factor used. The retail price announced by R1 Wurks is 79.99 dollars.
