Please Note:
The springs are priced / boxed individually.
Role of coil spring:
• Support the vehicles weight and absorb the impact of the road condition
• Increase the life of the shock absorber and other suspension components including tyres
• Together with shock absorbers they make up the vehicles suspension system which keeps the tyres in contact with the road.
Why change Coil Springs?:
• To return the vehicle to the correct ride height
• To maintain tyre contact with the road surface
• To improve road handling
• To improve wheel alignment
• To save money by increasing shock absorber life
When should Coil Springs be changed?
• When broken – always replace in axle pairs
• When fatigued (sagging) – always replace in axle pairs
• Shock absorbers should also be replaced at the same time – always replace in axle pairs.
SPECIFICATION:
• Hot & Cold coiling technology
• Manufactured to ISO 9001 standards
• Shot-peening significantly increases the fatigue life of the spring
• Surface preparation and coating ensures excellent corrosion resistance
• Side load technology (banana springs) available
• Full range of OE design taper wire miniblock technology available (RJ Series). Alternatively, a competitively priced aftermarket constant wire design is available (RX Series)

Springs are an essential part of your car's suspension system. They absorb much of the initial road shocks. SPAX SSX spring kits are ideal if you want to lower your car to get cool looks and a sportier ride.
Performance Lowering makes your car less top heavy. When combined with SPAX optimised spring rates, you get less body roll, reduced bottoming out and better handling. Most SPAX spring kits are progressively wound. This offers a softer ride at low speeds and a stiffer ride at high speeds, when you need it most.
SPAX springs are manufactured and tested to German TÜV standards but doesn't come with an actual TÜV certificate.
They are made using only the finest Chrome Silicon steel, They are shot peened, oven cured (to prevent sagging) and epoxy powder coated (to give the best possible corrosion resistance).
Safety Reduced body roll, predictable handling and a dependable quality product will help keep you and your car on the road.
Value SPAX's massive buying power, superior manufacturing systems and "Factory Direct" pricing allows you to buy a premium product at what is often below the price of a "budget brand".

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.
