I have a set of Cayman S 18" wheels and tires that I bought 6 months ago as new take-offs. I am going to turn my Cayman back in off of its lease, and do not want to make a gift of these upgraded wheels to the leasing company. So. I am interested in trading my 18" S wheels and tires (6 months old, in perfect shape) for your stock 17" wheels and tires, plus a cash difference to be discussed. Let me know if you are interested. I am in Florida.
