Product Details

The new KW V4 Racing sport coilover kit is a further development of our GT4 customer sports applications and therefore the ideal performance tool for track tools and purebred racecars. In comparison to a KW V3 Clubsport coilover kit, the KW V4 does not come with a parts certificate.

In consequence, this coilover kit is exclusively made for track day and circuit uses with motorsport tires. The KW V4 is independently adjustable in lowspeed and highspeed compression and lowspeed rebound.

Uncompromisingly designed for competition

The KW V4 coilover kit is a vehicle-specific motorsport application and is available in different versions for numerous vehicles

Many of our motorsport clients decide on a KW V4 when they plan on taking part in track days with non-road legal vehicles or when they are not ready to use a homologated customer sport suspension. In its entire setup, the KW V4 is vehicle-specifically designed for the Nurburgring Nordschleife as regards its axle geometry, clearance, damping rate, spring rate, spring travel, and wheel loads.

Directly in our headquarters in Fichtenberg, we manufacture the KW coilover kit with MacPherson spring struts made of stainless steel and an inverted monotube damper cartridge. The piggyback (external reservoir) is mounted directly at the suspension.

With the KW V4, it is possible to adjust the characteristic damper design to the individual needs of the customer. Within 15 clicks in lowspeed compression, 12 clicks in highspeed compression, and 18 clicks in lowspeed rebound, a variety of individual possibilities for different racetracks are available.

Standard Features

  • Aluminum Unibal top mounts (adjustable camber, depending on axle geometry and car)
  • Linear high-strength racing springs
  • Lowspeed compression adjustable
  • Highspeed compression adjustable
  • Lowspeed rebound adjustable
  • Galvanized alloy steel MacPherson spring struts
  • Rear axle damper housing made of aluminum alloy (depending on the version)
