Product Information

Coilover Set

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.

ST SUSPSENSION ST AX
I was looking for a suspension set up for my m340 xdrive and i’m very picky when coming to ride quality, need it to be very smooth, be low without hurting my back or feeling the bumps/road as much. This suspension Nails it right on the spot. I do heavy roads trips with my m340 and ride quality was my biggest issue, i don’t have adaptive suspension. I have Stock M suspension, it’s harsh on bumps, it was alright when doing trips, always hurt my back or was tired of the ride. These were exactly what i was looking for, Very smooth, absorbs bumps way better than stock M suspension, ride quality is amazing, less body roll. This is one of the best purchases i’ve made. Night and day difference.

Quality review
I was looking for a good set of coilovers for my BMW M340i that could improve handling while maintaining decent ride quality for daily driving. Before buying, I spent quite a bit of time researching different options ranging from KW Variant 3 Coilovers to BC Racing kits. Ultimately, I decided on the ST XA Coilovers, which sit in a very interesting middle ground in terms of price and performance. While the ST XA does not offer as many independent adjustments as the KW V3, it still provides rebound damping adjustment, which is more than enough for most street-focused builds. One of the main reasons I chose ST is that ST Suspension is manufactured by KW Automotive, using very similar engineering, damper technology, and internal components. The main difference is that ST uses galvanized steel bodies instead of KW’s stainless steel “inox-line” construction, which helps keep the cost significantly lower. For my build, this made the ST XA a great value because it delivers KW-level engineering at roughly half the price of the KW V3 setup. After about two weeks of driving with the ST XA installed, the improvement is noticeable: The car feels much more planted in corners, body roll is reduced compared to stock suspension, the ride quality is firmer but still comfortable for daily driving, the adjustability allows you to fine-tune the balance between comfort and performance. My BMW M340i is lowered with the ST springs sitting close to the tire, and even at this ride height the suspension remains composed without excessive harshness. Overall, if you're looking for a high-quality coilover setup without paying KW V3 prices, the ST XA is a very strong option. It offers the core performance features most drivers actually use while maintaining solid ride comfort and build quality. For a street-driven performance build, I think it hits the sweet spot between cost, adjustability, and driving feel.

Question Posted by Travis
does this also fit the 2024 m340i xdrive?
Answer (Posted by FCP Euro Products Team)
These likely do, and appear to fit based on shared components. I would recommend contacting ST directly for confirmation as they currently do not list anything past 2023 as compatible.
