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.

Lowering Springs – Improved Stance, Handling and Ride Control
Lowering springs are suspension upgrade components designed to reduce ride height, lower the vehicle’s centre of gravity and improve handling performance. By replacing standard factory springs with shorter, higher-rate springs, lowering springs enhance cornering stability, reduce body roll and give the vehicle a more aggressive, purposeful stance.
At Design911, we supply lowering springs from trusted OE and performance suspension brands, engineered to maintain ride quality while delivering improved control. Whether you’re refreshing worn suspension components or upgrading for fast-road performance and visual impact, lowering springs provide a balanced and effective suspension upgrade.
What Do Lowering Springs Do?
Lowering springs replace standard suspension springs to reduce
ride height and increase spring rate, helping the vehicle sit lower and respond
more precisely to steering input. Their key benefits include:
- Lower centre of gravity for improved stability
- Reduced body roll during cornering
- Improved steering response and road feel
- Enhanced vehicle stance and appearance
When correctly matched to compatible dampers, lowering springs deliver noticeable handling improvements without sacrificing everyday usability.
Why Upgrade to Lowering Springs?
Lowering springs are a popular upgrade because they offer:
- Improved handling with minimal modification
- Better balance during spirited driving
- Reduced squat and dive under acceleration and braking
- A sportier, performance-oriented look
Performance lowering springs are developed through extensive testing to maintain correct suspension geometry, ride comfort and durability.
When Should You Replace or Install Lowering Springs?
Lowering springs should be installed when:
- Factory springs are worn or sagging
- You want improved handling for fast-road driving
- You are upgrading dampers or other suspension components
- Enhancing vehicle stance is part of a performance build
Replacing springs during suspension servicing ensures optimal performance and avoids uneven ride height or handling issues.
At Design911, our lowering springs meet high engineering standards for fitment, reliability and performance.
