    Unfortunately, my rear bumper was damaged by a smack from another driver, so I decided to upgrade. I already had my eye on the GT4 rear diffuser. Suncoast over-nighted the parts to me (the package was on-sale) and I had a body shop do the installation. There are multiple parts and heat shields, and the rear bumper cover has to come off. The end-result is a more aggressive and custom look, that complements other visual upgrades I have made to the car (new exhaust tips, tinted rear tail lights, clear side markers, sport mirrors, etc.)

    Looks great. Painful to install

    The GT4 rear diffuser certainly looks great on my Cayman S, but be prepared to spend some time removing the old one and installing the new. Patience is required, especially if you don't want to damage anything. Blue painters tape should be used to protect the bumper cover and several "tricks" are needed to free the old diffuser. Center section is the hardest and loosening the tailpipes and angling them down gives you some more room to see things.

    I love my Cayman S but I didn't like seeing the oxidizing mufflers through the stock rear diffuser. The GT4 rear diffuser solved this problem and added a much more aggressive look. I had this installed by my dealer who took two hours for installation.

    I installed the GT4 Diffuser and was immediately impressed with its looks. I think it adds a much better look to the rear of my GTS.
