Low weight and low friction
Commitments to continuously improve in motorsport products, have resulted in the next level in the KONI range. Requirements from top teams asked for a compact design to improve in weight, aerodynamics and also friction. Consequently the 2612 Series were brought to light.
The 2612 series are based on the proven technology of the 2812MKII two-way adjustable damper, being used by many race teams over the last decade. The major difference with the 2812MKII is the smaller diameter and the low friction parts being the standard feature.
They have stroke ranges from 29 to 109 mm.
The design and operation of the 2612 series racing damper is again a unique proof of KONI’s reputation as the leader in the field of damper technology.
They are specifically designed for competition purposes and offer full adjustability while fitted on the car. Their precision adjustment mechanisms allow maximum control over the damping forces generated, especially in the low speed damping range.
To achieve this, the 2612 series do not rely on the commonly used needle valves. Instead, a superior and advanced adjustment cartridge controls the opening and closing of valve loaded ports. Positive lock detents assure that each port can only be either open or closed. The result is that the cartridge will always accurately reproduce a set of eight pre-programmed damping curves.
Various cartridges are available, each with its own set of characteristics. A pair of cartridges is housed in the main piston, one for bump, one for rebound. Together they can modify any given basic valving in 64 different ways. By having all forces generated by the piston assembly, the control of the damper over the suspension is instant and precise, decisive and smooth. A separate bulky reservoir is not needed and the installation can be kept simple, compact, lightweight and clean.
Besides being developed and used in the Formula 3 Euro Series, the 2612 is standard equipped on the N.T. Formula S2000 series.
