I'd advise replacing with the heavy-duty versions and not with pattern ones; the non-OEM parts have a tendency to fail again after a couple of years whereas the cupra / gti parts survive very nicely indeed.
That's at least the reports off of the German Forum. You should be running a geometry check after this as the struts are *the* thing that will move the front geometry around as much as moving the subframe will, and so at least one setting can only be changed by shifting the strut around.
