If they are Sportline II be aware of the stiction problem.
I am changing mine to the new design struts in 2 weeks (still Sportline I but with stronger struts with longer and thicker rods).
My car used to have the Sportline II and they were replaced FOC from Powerstation during the first service (1000 miles) with the Sportline I it has now due to the issue Karma describes in the above thread.
