KW height adjustable springs kits are a great alternative to conventional springs to give you a more dynamic look and better driving dynamics.
When installing KW height adjustable springs, the steering behaviour and response of the standard dampers becomes more agile and all driver assistance systems plus comfort features of an adaptive series suspension remain with KW's vehicle specific developed spring set up.
With conventional lowering springs you have to decide on the lowering from the beginning, but not with the KW height adjustable spring kits. Depending on the vehicle specific application you can change the lowering within the adjustment range with the threaded spring perch when the springs are already installed. For example, the KW height adjustable spring kit for an Porsche 991 turbo allows you to lower the car in the range of 0-35 mm. You will not have any difficulties adjusting the lowering when changing your wheel/tyre combination.
KW Height Adjustable Spring Kit
Max Weight - F: - 785 R: - 955
Lowering Front(mm) - 20 -40
Lowering Rear(mm) - ca. 25
Please Note
Front and rear height-adjustable (front and rear springs with height adjustment, usage only with factory dampers)
Product Features:
- Improved steering behaviour and response
- Compatible with OEM dampers
- Adjust ride height even when springs are installed

Dual Stacked, Triple Rated Spring Technology
Our award-winning adjustable modular suspension solutions were developed and engineered for safety, comfort, and performance. They come with a lifetime warranty.
The relatively low initial spring rate absorbs small bumps in the road, thereby increasing grip. It then transitions to a secondary spring rate which enhances your vehicle handling during cornering, giving you the ultimate control of your driving experience.
The third and stiffest rate assists by resisting sudden dynamic movements such as during acceleration, braking or swerving to avoid an obstacle. In doing so your Porsche remains composed as traction is retained at each wheel for optimum grip on dry or wet roads.
MSS Front Controller (Spring)
The orange springs have been designed to manage front ride activity, enabling maximum comfort
Dual Stacked
The MSS Springs are designed to work in unison, ensuring that the sudden vehicle movement is effectively controlled. The dual-stacked arrangement can be carefully specified to operate at different spring rates. This gives a huge range of tuning possibilities.
MSS Rear Ride Enhancer
The MSS rear ride enhancer keeps the MSS R/ride controller properly seated against the suspension, so you can push the limits of you car. When cornering hard and the wheels lift off the ground, the active coils of the tender spring hold the MSS ride controller in position
Triple Engineered Technology Benefits
Thanks to its patented Triple Stack Spring Technology, MSS can for the first time deliver improved performance, comfort and safety, within one product - and without compromise.
Superior Performance
Experience a total transformation of your Porsche's handling when driven hard. Two active springs and three separate spring rates deal with a much wider range of situations when driving near the limits. Distinct benefits from the reduced roll and pitch - whether it be dive or a squat, enables you to turn in sharper, brake later and accelerate earlier respectively.
Enhanced Safety
Upgrade your ride quality and enjoy a smoother, quieter and more composed drive. Shocks and vibrations caused by bumps and the roughness of the road surface are both more effectively absorbed by the dual stacked, triple rated springs - rather than being transmitted through to the cabin as jolting and distracting road noise.
Unparalleled Comfort
Drive with confidence knowing that you are protected against loss of traction and control - even on wet roads. Within the dual stacked, triple rated spring arrangement are springs specifically designed for safety. These reduce the violent spring oscillations associated with hazardous and emergency situations, quickly transferring these forces to the shock absorber. At this point tyres recover contact with the road - and control is regained.
Technology
Simply bolt on for instant performance
Easy installation with no modifications needed
As a spring-only solution, our products are quicker and less expensive to fit, set-up and remove. Additionally installation and removal requires no drilling, cutting or bending. All highly desirable for lease car drivers.
Adjustable Ride Height
Quickly and easily change ride height, right back to original - without removing the product.
Both front and rear ride height is easy to control and adjust - with unique mid-mount adjusters available for vehicles with limited access. Unlike traditional aftermarket suspension, our products can be returned to original ride height - giving extra clearance for winter driving for example.
Eibach Technology
World leading manufacturer - all MSS spring components are produced by the world's greatest spring manufacturer, to their highest specification.
Our unique dual stacked, triple rated springs are manufactured by Eibach to their top of the range ERS specification - the highest quality tolerance springs available on the market.
We believe our products represent unbeatable value when compared to traditional aftermarket suspension options. Additionally, we make it easy for you to upgrade with a fixed pricing policy across all products.
Peace of mind
Quality controlled following the most stringent technical standards in the market.
Our springs are precision manufactured in a TUV approved facility to TUV specifications. Every product is sold with a lifetime warranty.

For cars WITHOUT Hydraulic Lift System (Option 474)
This kit is specifically designed for rally-asphalt use. It not only stabilizes the vehicle but also effectively absorbs bumps from uneven road surfaces.
The standard setup includes a wishbone coil over design with 44mm pistons in the struts. These larger pistons allow for a greater volume of shock oil, ensuring durability and preventing shock fatigue, even with prolonged use.
- The Pillowball Top Mount allows for camber adjustments on the front tires, improving cornering performance and vehicle stability.
- The spring rate and damping settings are primarily designed for rally asphalt use.
- This unit includes adjustable ride height and a 36-way damping system to accommodate different road conditions.
- The ride height can be lowered by 60–100mm from the original factory setting, as a reference.
- Even at high speeds, it prevents lateral sliding during sharp turns.
- This product is not suitable for street, rally gravel, or rally snow conditions.
- For any applications not listed, we offer customization to meet specific customer requirements.
- The 3D Pillowball Top Mount also allows for both camber and caster adjustments as an option for customers.
- All applications listed on our website are for 2WD models unless otherwise specified as 4WD.
Pillowball Top Mount (fitted to front shock absorber assemblies)
The pillowball top mount allows for camber angle adjustment, improving your vehicle's handling and stability by up to 10%. However, it may produce a slight noise when going over large bumps.
