ATTENTION
Before you can continue, you must agree to all of the following terms:
The RM Series is comprised of a damper cartridge secured within a threaded outer body. This specific design requires a lubricating grease to be applied during the assembly process between the two damper and threaded body to avoid metal-to-metal contact. In order to keep the two components from touching each other and generating noise transmission you will need to periodically clean out the old grease and apply new grease.
This is a simple process that can be done with just a few common tools. It does not require you to open the internals of the dampers themselves and therefore you do not need to have the dampers re-pressurized after carrying out this procedure. Please contact us on info@mlperformance.co.uk for more information and a step-by-step guide on how to complete this maintenance.
As a result of this required maintenance, we do not recommend the RM Series for road use over the BR Series or ER Series.

KW V4 Racing - Triple adjustable racing technology for circuits
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 Racing 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 Racing is independently adjustable in lowspeed and highspeed compression and lowspeed rebound.
Uncompromisingly designed for competition
The KW V4 Racing 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 Racing 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 Racing 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 V4 Racing 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 Racing, 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.
- 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)
- BMW E90 2005-2013
