Your RS5 B9, Your Setup: KW Coilover Suspensions & Height-Adjustable Springs
The Audi RS5 B9 (Coupé/Sportback) comes equipped with a 2.9-liter V6 biturbo engine and is positioned by the manufacturer as a supremely capable performance GT for both everyday driving and long-distance travel. With a coilover suspension or height-adjustable springs from KW suspensions, you can now customize the feel of your RS5 yourself. Both the suspension and the springs allow for stepless lowering for vehicle models with and without DRC (Dynamic Ride Control). Those who opt for the KW V3 or KW V4 coilover suspension can not only lower the vehicle but also individually adjust the damping characteristics. In this case, the DRC is simply deactivated and can be reactivated at any time. With the height-adjustable coilover springs, the stock dampers remain in place.
Audi RS5 B9 Suspension: A Comparison of Stock Tuning and KW Coilover Suspension & Springs
The Big Suspension Comparison
The Factory Suspension
The Audi RS5 B9 is engineered from the factory for stability, traction, and confident speed. The quattro all-wheel-drive system with a 40:60 torque split ensures that the 450 PS is reliably transferred to the road. The optional sport differential also actively distributes torque between the rear wheels. The result is a confident performance GT that combines everyday driving, long-distance travel, and sporty driving in a single car. According to Audi, the RS sport suspension is tuned to be about 15% stiffer than that of the S5, while the RS sport suspension plus with DRC adds hydraulic roll and pitch stabilization. This is exactly where KW comes in: It shifts the stock compromise to exactly where you want it. You can adjust the ride height and damper characteristics yourself, giving you more control over the body and more precise steering response.
KW V3
You can actively address the minor flaws in the stock suspension of the Audi RS5 B9 with the KW V3: With this coilover kit, you can adjust the compression and rebound damping separately. This allows you to fine-tune the damping precisely to your driving style. For example, the compression stage provides more grip, better steering response, and less body roll without having to adjust the rebound stage, which is matched to the spring rate. The coilover suspension system features continuously adjustable ride height within the tested range (5–25 mm or 10–30 mm at the front and rear, depending on the body variant and DRC).

Does my RS5 have DRC?
Before installing a KW coilover suspension kit, you need to check whether your Audi RS5 (B9) is fitted with DRC (Dynamic Ride Control). This must be shut down in advance using the enclosed cancellation kit. The DRC feature is part of the optional RS Sport Suspension Plus package; otherwise, the standard RS Sport Suspension is installed. If you’re not sure, simply check your equipment list.

The Technological Highlights of Our Products
Customized lowering
This coilover suspension offers maximum possible lowering, customized to your vehicle model. You can also change this at any time after installation.
Adjustable rebound (low speed)
You'll notice the difference with every click! Here, you can adjust the low-speed rebound with 16 clicks. This adjusts the ride characteristics, making them either harder or more comfortable.
Adjustable compression damping (low speed)
You can fine-tune the low-speed compression damping even after installation. The vehicle's handling and stability will benefit from 12 clicks.
Composite spring disc
The height-adjustable KW spring plate is made from a resistant and friction-optimised polyamide composite material with a stainless steel insert. In contrast to anodised aluminium adjustable spring plates, the polyamide composite material prevents possible oxidation.

Frequently Asked Questions from the Community
Is the RS5 B9 still suitable for long-distance driving with a KW coilover suspension?
Yes. Both the KW V3 and KW V4 are designed for everyday driving as well as longer trips on the road, in city traffic, or on the highway. If you want more comfort on long drives, you can use the adjustment wheels to achieve smoother damping in no time at all.
Does lowering the car make sense with my wheel/tire combination?
That depends on the rim size, offset, and tire width. The parts certificate includes vehicle-specific information and requirements for safe installation, and serves as the basis for registration. For custom wheel-and-tire setups, it’s best to consult your KW dealer beforehand.
How much does the handling change compared to the stock suspension?
That depends on the suspension product and the settings. With a KW coilover suspension, you can specifically adjust body roll, steering response, and load transfer behavior using the adjustment wheels. In contrast, our coilover springs are exclusively height-adjustable and give your RS5 an even sportier look. The stock shock absorbers remain in place, and the handling remains close to stock, combined with a subtle lowering.
Do I have to do without certain features on the Audi RS5 B9 with DRC?
When installing a KW coilover suspension (V3, V4) in an Audi with DRC, the stock damper control system is deactivated on a vehicle-specific basis. You can then adjust the damping mechanically on the shock absorbers. If you want to keep the stock damping control, you can opt for the KW height-adjustable springs, as the stock damping system remains active with them. The deactivation of DRC can be reversed at any time.
