Porsche 981 Boxster Spyder - 2016
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.

Front and rear height-adjustable (front and rear springs with height adjustment, usage only with factory dampers)
Product Features:
