Description KW 39720308 Coilover Kit V4 RACING for BMW M3 (E30) 1986-1991

The KW V4 Racing sport coilover kit is developed from GT4 customer sports applications, making it a dedicated performance solution for track tools and racecars. Unlike the KW V3 Clubsport coilover kit, the KW V4 Racing does not include a parts certificate and is designed exclusively for track day and circuit use with motorsport tires. The kit offers independent adjustment of lowspeed and highspeed compression as well as lowspeed rebound.

This coilover kit is uncompromisingly designed for competition. It is a vehicle-specific motorsport application and is available in various versions for numerous vehicles. Many motorsport clients choose the KW V4 Racing for track days with non-road legal vehicles or when a homologated customer sport suspension is not required. The setup is specifically engineered for the Nurburgring Nordschleife, considering axle geometry, clearance, damping rate, spring rate, spring travel, and wheel loads.

Manufactured at the headquarters in Fichtenberg, the KW V4 Racing coilover kit features MacPherson spring struts made of stainless steel and an inverted monotube damper cartridge. The piggyback external reservoir is mounted directly to the suspension. The damper characteristics can be adjusted to meet individual requirements, with 15 clicks for lowspeed compression, 12 clicks for highspeed compression, and 18 clicks for lowspeed rebound, allowing for a wide range of setups for different racetracks.

- Aluminum Unibal top mounts with adjustable camber (depending on axle geometry and vehicle) - Linear high-strength racing springs - Independent adjustment of lowspeed and highspeed compression, and lowspeed rebound - Galvanized alloy steel MacPherson spring struts and aluminum alloy rear axle damper housing (depending on version)
