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

Improve handling with reactive rear steering

Enhance your 411 chassis by fitting the Serpent 401618 Reactive Rear Steering system. It introduces dynamic rear geometry so the car responds more predictably through changes of direction.

Rear toe that adapts with suspension movement

The system changes rear toe during compression and droop, helping to maintain tyre grip through corners. That adaptive behaviour boosts stability without dulling front-end response.

Tailor the toe-change to your setup

Choose from several adjustment settings to control how much toe varies under load. Tweak the range for traction-focused setups or for a looser, more agile rear end depending on track demands.

Designed for ERYX and classic 411 platforms

Serpent 401618 fits ERYX 2.0 and 3.0 as well as earlier 411 chassis, and it supports both aluminium and carbon chassis constructions for flexible installation options.
