Serpent 401618 Reactive Rear Steering Kit for 411 Chassis  [SER401618]

Upgrade your 411 with responsive rear steering

Take lap times to the next level with the Serpent 401618 Reactive Rear Steering (RRS) System, engineered for the 411 series. This kit introduces controlled rear toe movement to deliver sharper corner entry and more predictable mid-corner feel.

Adaptive rear toe for better turn-in

The RRS allows toe-in to change through suspension travel, so tyres maintain contact and grip during compression and droop. The result is improved traction without sacrificing steering precision across different track conditions.

Fine-tuneable settings to match your style

Adjustable toe-change options let you dial in how much rear geometry shifts under load. Choose minimal change for a neutral balance or increase toe shift to add rear traction when you need it most.

Works with ERYX and multiple 411 versions

This Serpent system fits ERYX 2.0 and 3.0 along with older 411 variants, and it is compatible with both aluminium and carbon chassis layouts for flexible installation across setups.
