This Porsche Boxster had leaking front struts at just over 100,000 miles. We removed the struts and replaced them with Bilstein heavy duty units. Another option that costs a little more money but is a nice improvement is the Bilstein pss10 kit. It features a 10 way adjustable strut so you can fine tune the ride for street or track use. It also includes adjustable spring perches and progressive springs. The adjustable perches allow us to set a custom ride height based on the customer's needs and corner balance the car for optimum performance.
