The Serpent 903020 Viper 990 packs a narrow-profile chassis to concentrate flex where it benefits cornering and stability. The design supports detailed setup work so tuners can tailor behaviour to the local track surface.
The chassis milling lowers the radio tray and refines flex characteristics while minimising the central aperture under the tank. A centre weight bridge, adjustable from under the car, allows quick shifts to the mass balance for changing conditions.
The redesigned rear geometry reduces binding and introduces reactive toe dynamics for cleaner rotation. The front steering blocks use an eccentric aluminium insert to change roll-center and accept either trailing or leading steering options.
A lightweight two-speed shaft and balanced pulley setup reduce parasitic loss for better acceleration. Drive shafts are crafted from spring steel to resist bending and keep power transfer consistent under load.
Adjustable camber, caster and multiple Ackermann inserts let you fine-tune steering response and tyre wear. The accessible layout and quick-change levers simplify setup swaps between practice runs.
This Viper 990 is a solid base for racers who enjoy setup work and want a chassis that responds predictably to adjustments. It balances durability with performance-focused features.
