ST Suspension

ST: An American Tuning Classic

The ST brand originated in California in the early 1980s under the name Suspension Techniques. Soon, thanks to the combination of modern technology and high-quality materials, it gained a large market share in the American tuning market. The brand enjoys great popularity in America and beyond today, and that is partly due to the acquisition in 2005 by the German company KW Automotive. In the Netherlands, the products were sold in the first years under the name "Weitec" and later "Weitec made by KW".
Thanks to a new range of products (such as the ST Coilover kit program based on KW Variant 1 Coilover kit) and the use of KW's technological knowledge and experience, ST Suspensions currently has a range of suspensions for a wide variety of applications and a worldwide fan base that swears by the products of this brand.

The ST Sport Suspension

A series of products aimed at significantly improving the driving dynamics of your vehicle without having to compromise on driving comfort. The ST Sport suspension uses so-called twin-tube dampers with a fixed damping and an adjusted rebound / spring ratio to offer a much sportier driving experience.
Depending on the make and model, the ST kits can lower your vehicle between 20 and 60 mm. The springs and dampers of the ST kits are perfectly matched to each other and the preset damping is not only adapted to the vehicle but also to the desired reduction. They are all tested according to strict German TÜV standards and can be used in total on more than 30 brands.

The ST X Coilover suspension

Are you going to lower? ST offers everything you need, no matter how extreme you want to go. They are based on the technology of KW Automotive, a guarantee for maximum quality and fantastic driving dynamics. They also allow you to adjust everything very conveniently after installation via the polyamide ring on a galvanized, repeatedly sealed, strut. By default you can expect a 35 to 65 mm reduction on both the front and rear axles.
In this way you can significantly reduce the body roll of your car during compression and thus obtain a very sporty steering. The car will also become more agile at higher speeds. The ST suspensions are specially designed with the least possible friction and a housing that can withstand high pressure next to a chrome-plated piston rod, all so that you get a suspension that is made to last.

This improves the balance and handling.
