Serpent 401640 2.0mm Aluminum Chassis for S411 Eryx 4.0 Carpet Setup  [SER401640]

Tune the Eryx 4.0 for Indoor Carpet Performance

The Serpent 401640 2.0mm Aluminum Chassis is a precision upgrade for the S411 Eryx 4.0 that focuses on indoor carpet track performance. It helps lower the centre of gravity and introduces controlled flex to improve mid-corner stability and traction feel.

Selecting the Best Chassis for Your Track

Serpent supplies three chassis choices for the Eryx 4.0 series so you can match chassis stiffness to your track and driving style:

• 401639 - 2.0mm Carbon Chassis: Suited to high-traction surfaces with a very stiff layup that minimises flex for crisp steering response.
• 401640 - 2.0mm Aluminum Chassis: Built for indoor carpet use, with a balance of flex and rigidity and lower side rails to aid cornering control.
• 401641 - 2.25mm Carbon Chassis: Offers a bit more compliance than the thin carbon option, useful on rougher asphalt or mixed outdoor circuits.

The aluminum option gives versatile handling on carpet while still allowing drivers to tune balance through setup changes and shocks.
