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

Porsche Boxster (986) 2.5L 1996-99
Porsche Boxster (986) 2.7L 1999-04

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)
