Another one of our customers, upset with his ride height approached us for a solution for his car. We went with the KW Suspension Height Adjustable Spring kit aka H.A.S.
The KW HAS kit utilizes the OEM shocks which retains the OEM dynamic suspension on the car. Drop range for the front is 0 to .8 inches while the rear is 0 to 1.2 inches. You can drop the height where you like as opposed to any other spring setup!
