One of the best first modifications to any car is to lower it. And if you're going to do it, do it right the first time. With that said we had a guards red Porsche 911 Carrera S in the shop for a KW HAS kit install. The HAS (height adjustable suspension) kit is a great option for the 911 as it offers individual heigh adjustability of the original shocks. It maintains the factory electronic damper control so there will be no error lights after installation. The KW Has system lowers the vehicle 15-35mm which is more than adequate for the Porsche. The install went smooth as KW provided clear and concise instructions for their kit. After the install was complete, we lowered the car back on the ground and took measurements to ensure all four corners were equal before performing a four wheel alignment.
