A car you love should feel rewarding long after the first stretch of smooth pavement. The way it settles after a bump, responds to a steering input, and carries itself through a corner all contribute to the experience. If your next upgrade is about making the car feel more composed, suspension deserves a place near the top of your list.

At Extreme Power House, our KONI selection gives you several ways to approach that improvement. Explore Sport dampers, Special Active shocks, STR.T components, and suspension kits for a range of BMW, Audi, Volkswagen, Mercedes-Benz, Porsche, and MINI applications.

Whether you are refreshing an older enthusiast car, planning a suspension upgrade for your daily driver, or pairing dampers with a more purposeful spring setup, KONI offers choices that let you build around how you actually use the vehicle.

Give the Chassis the Attention It Deserves

There is a particular satisfaction in a car that responds cleanly to your inputs. Good suspension control helps make the whole vehicle feel more connected, from the moment you turn the wheel to the way it settles as the road changes.

Springs support the vehicle and influence its ride height. Dampers control suspension movement. Choosing the right combination matters because both work together every time a wheel encounters a bump or the body moves during braking and cornering.

That makes a damper upgrade a worthwhile part of a complete build. You may already have the wheels, tires, and engine modifications you wanted. Refining the suspension adds attention to the part of the car that manages those upgrades on the road.

KONI’s range gives customers different approaches to that task. You can prioritize damping adjustment, explore a system that responds mechanically to different suspension inputs, or select a straightforward replacement with preset damping.

KONI Sport: Adjustment for the Enthusiast Who Likes to Refine the Setup

Recognizable by its yellow finish, KONI Sport is an appealing choice for drivers who want greater involvement in their suspension setup.

The Sport range offers adjustable rebound damping, allowing you to refine how the damper controls the suspension as it extends. The adjustment method depends on the individual part; some applications provide external adjustment, while others use a different procedure.

For an enthusiast developing a car over time, that adjustability adds flexibility. Your spring choice, driving preferences, and overall suspension setup can all influence the damping setting you prefer.

It also makes Sport worth considering when suspension is a central part of your project. If you enjoy comparing setups and making deliberate changes, adjustable dampers give you another tool for shaping the car’s response.

Our selection includes Sport applications for vehicles such as the BMW F30 xDrive, Audi A3, Audi A4, and Porsche Boxster 986. Select the part designed for your chassis and suspension configuration, then follow its specific adjustment instructions.

KONI Special Active: Control and Comfort in One Package

A performance upgrade can also serve the driver who wants a comfortable, composed road car. KONI Special Active is designed around that goal.

Special Active uses KONI’s Frequency Selective Damping technology. Its mechanical valve system responds differently to suspension inputs, helping control larger body movements while allowing a more compliant response to sharper road disturbances.

The technology works without adding sensors, control wiring, or a driver-operated adjustment interface. For owners who want the suspension to manage those changing demands automatically, that is part of its appeal.

Picture a car that spends the week commuting and the weekend on a favorite winding road. You want it to feel settled through corners, but you also care about how it deals with expansion joints and broken pavement. Special Active addresses those priorities within the damper itself.

Our KONI selection includes Special Active applications across sedans, wagons, sports cars, and crossovers, giving customers plenty of platforms on which to explore that balance.

KONI STR.T: A Straightforward Route to a Suspension Refresh

KONI STR.T, identified by its orange finish, offers preset, non-adjustable damping.

That makes it appealing to owners who want to install application-specific shocks or struts without planning around manual damping adjustments. Each component is developed for its intended vehicle, giving the upgrade a clear and practical role in a refresh.

At XPH, STR.T listings include applications such as the Audi A4, Audi A6, Audi TT, and Mercedes-Benz W204 C-Class.

For someone bringing a familiar car back into regular use or replacing tired suspension components, this range is worth exploring. You can focus on choosing the right parts and reviewing the rest of the suspension while the damping specification is already established.

It is also a useful option when your project calls for simplicity. You may enjoy personalizing the car without wanting every component to introduce another setting to manage.

BMW: Suspension Choices for Sedans, Coupes, and Crossovers

BMW owners can explore several KONI product families in our catalog.

For selected F30/F31 3 Series applications, Special Active rear dampers provide an option for a road-focused suspension refresh. The 8245 1319 listing covers specified rear-wheel-drive and xDrive configurations, with exclusions that vary by model and factory suspension.

Customers looking for adjustable damping can explore separate Sport listings, including front components for selected F30 xDrive applications.

For a broader change, our catalog includes 1145 Sport Kits for selected BMW 335i, 340i, and 435i models. Separate listings cover particular rear-wheel-drive, xDrive, coupe, and convertible applications, allowing you to choose a package around the vehicle’s actual configuration.

BMW crossover owners have options, too. The selection includes Special Active components for the F48 X1, alongside other BMW applications.

A 3 Series suspension refresh and an X1 upgrade serve different purposes. KONI gives owners of both a reason to look beyond the factory replacement path and choose hardware around the driving experience they want.

Audi: Match the Damper to Your Factory Suspension

Our KONI Audi selection spans several generations and suspension designs.

Examples include Sport and Special Active front dampers for selected 2005–2013 Audi A3 applications, along with multiple product families for the 2002–2008 Audi A4.

The range also includes separate Sport front listings for 2009–2013 A4 models with and without S-line suspension. That distinction matters because the factory suspension specification helps determine which component belongs on the car.

Audi TT owners can explore selected Sport and STR.T listings, while A6 owners have options with restrictions such as the exclusion of air suspension on particular parts. B9 A4/S4 Special Active listings introduce further details, including clamp diameter and electronic suspension exclusions.

For the customer, these choices create an opportunity to select a damper around both the chassis and the intended result. Decide whether you want adjustment, Special Active’s damping approach, or a preset replacement, then narrow the options to your Audi’s exact equipment.

Volkswagen: Golf and SportWagen Fitments with Important Details

Volkswagen owners will find KONI applications for selected Golf, SportWagen, Golf R, Passat, and Tiguan models.

The Golf 7 listings illustrate why suspension shopping benefits from a little attention to detail. Our catalog includes separate Special Active front dampers for 50mm and 55mm strut housings.

Rear applications also differ. A Golf with independent rear suspension uses a different suspension arrangement from a model with a torsion beam, and our listings distinguish those configurations.

Once you identify your setup, you can focus on the product that serves your goal. A SportWagen owner refreshing a well-used commuter may prioritize comfort and control, while a Golf enthusiast may be building around a more involved suspension project.

KONI’s application-specific approach gives both customers a useful starting point. Choose the correct dimensions and suspension layout, then compare the available damping options.

Mercedes-Benz, Porsche, and MINI: More Platforms to Explore

KONI’s appeal extends well beyond BMW, Audi, and Volkswagen.

For Mercedes-Benz W204 C-Class owners, our Special Active front listing provides an option for specified applications. Its exclusions include electronic and air suspension, heavy-duty suspension, 4MATIC, and self-leveling systems. Separate W205 C-Class and W212 E-Class components also appear in our selection.

For Porsche Boxster 986 owners, KONI offers another direction for maintaining an engaging sports car. Our Special Active front listing covers specified 1997–2004 Boxster applications, and Sport front struts are also represented in the catalog.

A suspension refresh can be a satisfying investment in a car you intend to keep. If you enjoy the Boxster’s compact proportions and mid-engine character, the chassis deserves the same attention as its appearance and engine.

MINI Countryman F60 owners can explore Special Active components shared with listed BMW X1 F48 applications, including separate front and rear parts. That brings another choice to customers who want to refine the feel of their crossover.

Matched Suspension Kits for a More Complete Change

If your plans include changing the springs as well as the dampers, explore KONI’s suspension kits.

The 1145 Sport Kit combines adjustable Sport dampers with matched lowering springs. For the appropriate application, that gives customers a coordinated package rather than requiring them to select each main component independently.

A matched kit is worth considering when your goals include both chassis behavior and a lower stance. Review the specified lowering, vehicle restrictions, and included components for the exact kit you are considering.

Individual dampers remain an option when you are retaining compatible springs or addressing a particular part of the suspension. A kit becomes attractive when you want to make a broader change with components selected to work together.
