About KW Coilovers
Born on the track, raised for the street, KW is Europe’s leading supplier of suspension systems. KW offers suspension solutions for nearly every vehicle application. With our three product lines we cover all the requirements of the market. KW coilovers are offered in inox-line stainless steel technology and three different damping technologies for individual adjustment. It is no surprise why KW is the leader in coilover suspension. Their coilovers feature composite spring perches for easy height adjustment and more suspension travel.
The 3 Variants - KW is the only supplier, offering 3 different dampening technologies
Variant 1: sporty-harmonic with KW factory pre-setup dampening
Variant 2: sporty and personalized with adjustable rebound dampening
Variant 3: race technology for the road with adjustable compression and rebound dampening. This patented valve technology is unique.
KW with its commitment to quality worked to set the standard in coilover manufacturing as the only manufacturer using inox-line stainless steel technology.
KW "inox-line" coilovers with stainless steel technology are clearly superior to galvanized models with regard to corrosion resistance and in addition ensure smooth operation which was proven by the salt spray testing procedure that KW conducted in cooperation with the Technical University of Esslingen in 2002.
A total of 9 products from 6 different manufacturers were subjected to quality testing in the form of a salt spray durability test. After only 48 hours the common galvanized coilovers had isolated rust spots and after 200 hours they were not moveable any more. KW coilovers in inox-line stainless steel technology were easy to move and had no rust even after 418 hours.
These clear results strengthened our resolve to concentrate on the quality of the product in the interest of our customers and KW will only offer coilover suspension systems constructed in inox-line stainless steel technology.
Manufacturing and Adjustment
During manufacturing of KW Coilover suspensions, the highest quality materials are used to produce individual suspension solutions that enable customers to adjust vehicle height according to their wishes and needs. This can be easily achieved using the purple-colored aluminum spring collars by adjusting the position of the yellow coated springs upwards or downwards via a specially designed exterior thread.
In doing so, the vehicle height can be precisely adjusted, and customers receive exactly the result they want and/or need. The stainless steel strut housings are fitted to each vehicle, and are available in three different damping technologies. With this variety, KW Coilover suspensions in Variants 1, 2 and 3 can meet the exact requirements of every customer. The complete systems including high-quality yellow springs, purple aluminum components and Elastomer bump stops with integrated dust protection system, provide a unique comprehensive solution for a personalized vehicle suspension system that meets all performance and quality demands.
Salt Spray Test - KW Decisions Take Time - Exactly 418 Hours !
In cooperation with the Technical University of Esslingen, a total of 9 products from 6 different manufacturers were subjected to quality testing in December of 2002 in the form of a salt spray durability test in accordance with DIN 50021 SS. The object of this testing was to compare corrosion resistance of the various systems under consideration of environmental influences such as salt water. During the test simulation of over 418 hours, the samples were inspected at regular intervals, whereby the corrosion resistance of piston rods and threaded struts were evaluated, as well as the adjustability of the aluminum spring collars.
