I found a lightly used set of Cayman R dampers, which will be replacing the stockers in my 2009 base Cayman. They didn't come with any top mounts. My stock top mounts have 60K miles on them. Should I plan to re-use them or should I just splash out with new ones at this mileage, considering everything will be apart? Obviously I can examine the condition of the existing top mounts when I remove them, but wondering what the consensus is... Thanks.
