BMW ST XA Coilover Kit - ST Suspensions 18220011

Product Information

Suspension coilovers are a type of car suspension system that combines a coil spring and a shock absorber (damper) into a single, integrated unit. The name comes from “coil” (the spring) and “over” (meaning the shock is inside or over the spring). Coilovers are typically adjustable, allowing you to change ride height, stiffness, and sometimes damping settings, depending on the model.

Benefits of Coilovers:

• Adjustable ride height: Coilover suspension typically features a threaded adjustable spring platform, allowing adjustment of ride height for better handling, aesthetics, or clearance.
• Improved Handling and Stability: Coilovers usually offer better cornering performance and reduced body roll compared to stock suspension.
• Customizable Ride Comfort: Many coilovers allow you to tune stiffness and damping to balance comfort and performance.
• Better Weight Distribution: Some coilovers can be adjusted corner-by-corner to fine-tune handling balance.
• Enhanced Appearance: Lowering the car can improve the stance and overall look.
• Versatility for Different Driving Conditions: Ideal for street, track, or off-road setups depending on the coilover design.

About ST Suspensions

Founded in the early 80’s in Southern California, under the company name of Suspension Techniques. Suspension Techniques developed many innovative products and solutions in response to market demands. Utilizing quality materials, modern technologies, and streamline processes Suspension Techniques was able to provide excellent value for their product in the marketplace. Suspension Techniques soon established themselves as a recognized name in the Sport Compact suspension tuning industry. This success helped garner the attention of many enthusiasts and tuners resulting in a strong growth in the brand in the USA.

The Sporttech & Speedtech lowering springs along with the Suspension Techniques Sway Bar kits became a household name in the tuning scene in the 80's and 90's, being referred to in many circles simply as ST. In 1995 this attention attracted a new owner, Belltech Sport Trucks, who brought a whole new dimension to the ST lineup. With the acquisition ST was relocated from southern California to Fresno CA.

In 2005, the German suspension manufacturer KW automotive GmbH, well known internationally for their KW Coilover height adjustable suspension systems, purchased both Belltech Sport Trucks and Suspension Techniques and launched KW automotive North America Inc. With the name purchase and a formal name change of the brand to it’s current nameplate of “ST suspensions”. The infusion of the technology from ST’s new parent company took ST's game to a whole new level, increasing not only its application range coverage, but adding the innovative ST Coilover program, which was modeled after a galvanized KW Variant 1 coilover design.

With this influx of worldwide technology, staff, and engineering base ST boasts one of the largest application ranges and largest distribution chains of any suspension manufacturer in North America.
