About KW Variant 3 (V3) "inox-line" Coilovers
Unlimited individuality for performance & comfort
Damping forces can be adjustment separately in rebound & compression
KW's engineers have developed a sporty yet harmonious basic setup, as with any KW coilover kit. To be able to guarantee the perfect suspension setup, each kit is tested on the KW 7-post rig, as well as extensive driving tests on country roads, motorways and even on the Nürburgring Nordschleife. For years, the KW coilover kit Variant 3 inox-line is one of the top aftermarket products and is a benchmark for coilovers. It convinces sports car drivers, tuner, large-and small series manufacturer such as Alpina, MTM, Manthey, Oettinger and many more leading companies in the international automotive industry with its damping characteristics, quality finish and durability.
Advanced technology from motor sport
With the KW coilovers Variant 3 inox-line you will get much more than just a sporty lowering and excellent driving behaviour on all roads. It is based on KW's long experience as a suspension manufacturer and supplier for international motor sport, such as the touring car series ADAC GT Masters, FIA GT1, FIA GT3, International GT Open, WTC, VLN and the legendary ADAC Zurich 24h-race Nürburgring.
Similar to the racing coilovers from the KW Competition program, the KW coilovers Variant 3 inox-line can be adjusted independently in compression and rebound damping. This individual adjustment possibility is much appreciated by sports car manufacturers, tuners and drivers worldwide.
The perfect suspension setup for more driving pleasure
If you have already made your first performance modifications to your vehicle, the KW coilovers Variant 3 will compliment your upgrades. The patented KW-valve technology for separate adjustment of rebound and compression damping allows you to individually setup your suspension. The adjustable KW bottom valve adjusts the low-speed range of the compression level in twelve clicks.
You don't need any adjusting tools because of the patented compression adjuster at the lower end of the stainless steel housing. The adjustable compression damping with its twelve exact clicks allows you to manually influence body roll, without having to change the spring rate which optimally matches the rebound.
With the individually adjustable rebound setup of the KW coilover Variant 3 inox-line, you can directly influence the handling and comfort with its precise click adjustment. Depending on the vehicle type, the rebound valves of the KW twin-tube dampers on the upper end of the piston rod will be adjusted via an integrated adjustment wheel or a twist-adjustment wheel which is included in the delivery content.
By increasing the rebound force via the adjustment wheel body movements are reduced. You will have more stability during high speed cornering. If you change for example the wheel / tire combination (approved by the car manufacturer) to larger wheels, then with a KW coilover Variant 3 inox-line you will be able to adjust the car's handling perfectly.
High quality, individual and durable
The KW coilover Variant 3 inox-line kit and every single damper are subject to extensive quality tests during production to meet the high standards of our KW quality management. This is the only way we can meet our expectations to give up to five years warranty on our KW coilover Variant 3 inox-line when installed at one of our KW specialist dealer. KW coilover struts made of stainless steel are 100% rust-free and an unlimited life time.
Therefore the operation of the continuous lowering via the dirt-resistant KW trapezoid thread and the KW composite collar is also not affected after years. By the individual lowering with its continuous adjustment range, you can emphasize the sportiness of your vehicle visually. A feature that is very popular in the performance-oriented tuning scene.

My first dealing with Southern BM was a pleasant one. I had some springs and shocks installed and Sean was a delight to deal with. Knowledgeable, helpful and offered solutions when not everything went to plan. I would happily recommend them.

Sean arranged a Quaife LSD for my 135i and I couldn't be happier. He advised multiple seals and bearings needed replacing unbeknownst to me so these were done as well. Now I have a more reliable car and one with tonnes more mechanical grip!

I have used many mechanics over the years for the many different types of vehicles in our company fleet and southern BM is one of the very few workshops I can highly recommend. Andrew and his team are also really passionate about their work and it shows.
