Serpent 903020 Viper 990 4WD 1/8 GP Touring Car Competition  [SER903020]

Compact Chassis Performance of the Viper 990

The Serpent 903020 Viper 990 focuses on a narrow chassis platform to concentrate flex and improve handling precision on the circuit. The package is geared toward competitors who fine-tune geometry for peak performance.

Milling, Radio Plate and Weight Adjustment

Careful milling lowers the radio plate and changes flex behaviour while reducing the centre opening under the fuel tank for a neater mass layout. A centrally mounted, under-accessible weight bridge lets crews adjust balance swiftly.

Tailored Rear Kinematics and Front Roll-Centre Options

Rear suspension revisions enable reactive toe-change to reduce binding and promote cleaner corner exit. Front steering blocks accept eccentric aluminium inserts to adjust roll-centre and support both trailing and leading steering setups.

Balanced Transmission and Robust Drives

The drivetrain employs a lightweight two-speed shaft and a balanced pulley arrangement to limit drag and optimise power transfer. Drive shafts made from spring steel provide dependable strength under racing stresses.

Comprehensive Adjustment for Race Tuning

With adjustable camber, caster and multiple Ackermann choices, the Viper 990 allows precise setup for tyre life and steering feel. The open design and quick-change levers reduce turn-around time between runs.

The Viper 990 is a precise, adjustable platform aimed at racers who need consistent handling and comprehensive tuning options to lower lap times.
