Race-Ready Chassis Upgrade Serpent 401121

For drivers aiming to tighten chassis behaviour, the Serpent 401121 Aluminum Stiffener Posts are a solid upgrade. Specifically made for the S400 and S411 series, these posts reduce unwanted flex and help the car hold a predictable line. The machined aluminium construction gives a durable, repeatable platform for tuning.

Performance Advantages

Adding aluminium stiffeners raises the overall torsional strength of the chassis, improving steering precision and mid-corner stability. The reduced flex helps with consistent tyre load and makes setup changes more effective during practice and race day.

Fitment Notes and Installation Tips

These parts are manufactured to match the Serpent S400 and S411 mounting layout and fit using the standard hardware. Installation is quick and straightforward; however check fastener torque and clearances when installing alongside other upgrades to avoid interference.

Will these posts add much weight?

They add a small amount of weight but are lightweight relative to the stiffness they provide. The trade off usually favours handling improvements on most tracks.

Are any modifications required?

No chassis modifications are normally needed for S400 or S411 cars. Fit them into the existing slots and confirm alignment before final tightening.

Do they work with other setup parts?

Yes. Stiffener posts interact with shock setup and anti-roll bars, so expect to fine tune suspension and roll control after fitting to get the desired handling balance.
