Serpent 401639 - 2.0mm Carbon Chassis for S411 4.0 Track Use  [SER401639]

Stiff 2.0mm Carbon Chassis for the Serpent Eryx 4.0

The Serpent 401639 chassis plate is a high-stiffness upgrade intended for the Serpent Eryx 4.0. Constructed from 2.0mm carbon fiber, it targets high-grip racing environments where limiting flex improves predictability. Drivers will notice crisper turn-in and steadier mid corner behaviour with this setup.

Comparing Chassis Options by Track Type

Serpent offers three chassis variants for the Eryx 4.0 so you can adapt to different track surfaces and driving preferences:

• 401639 - Carbon 2.0mm: Optimal for very high traction tracks due to its rigidity and minimal deflection.
• 401640 - Aluminum 2.0mm: Preferred on indoor carpet for a more compliant feel and consistent weight distribution.
• 401641 - Carbon 2.25mm: A slightly more flexible carbon option aimed at outdoor asphalt where extra compliance helps traction.

Each chassis changes how the car responds under load, so choose based on surface grip and how much roll or bite you want. Carbon plates tend to favour aggression and precision while aluminium softens the response.
