Refine Handling with a Vertical Topdeck for Serpent 4X

If you want a more controllable Serpent 4X Touring Car, the Serpent 401738 Vertical Topdeck Set lets you reshape chassis behaviour. It incorporates two vertically oriented 2.5mm carbon fibre plates to affect how the chassis twists and returns.

Matched Carbon Fibre Plates and Adaptor Fit

The kit includes two identical carbon fibre plates that bolt to the front and rear suspension via machined aluminium adaptor plates. That configuration delivers linear torsional flex while curbing longitudinal and torsional tweak to aid consistency.

Selectable Stiffness for Setup Tuning

The vertical topdeck can be used with the kit's aluminium centre stiffener or on its own. Removing the H-shaped stiffener plate increases flexibility in the front and rear ends, allowing drivers to tailor balance to track conditions.

The main benefit is improved control over torsional behaviour; the plates allow predictable flex while reducing unwanted tweak for steadier cornering.
Yes. The vertical topdeck is compatible with the kit's aluminium centre stiffener, and you can switch it out to alter stiffness when tuning setup.
Start with the stock setup, then test with and without the H-shaped stiffener to find the desired front to rear balance. Make small shock and anti-roll bar changes as needed.
Indirectly. By reducing unpredictable twist, the car can run more consistently which may result in more even tyre wear over a race distance.
Inspect mounting points regularly, check for delamination or hairline cracks after heavy impacts, and ensure adaptor fasteners remain correctly torqued.
