PP has a great tech article on a cooling kit for 911 brakes

Also, 2nd the idea of Carrera brakes for an SC.
And while you are in there... Recommend replacing the front bearings. A really great project. When the hub is off the strut, recommend cleaning and media blasting the hub. Looks great when finished. Leave the old races in place until you are done cleaning the hub. Used rags stuffed into the hub to keep the media out. A bearing race kit is a great tool to have when replacing the bearing races. Of course, get a good set of bearings (e.g., Timken, etc.) is needed too. Pelican sells a really cool bearing grease packing tool. The Mobile One red synthetic bearing grease is good stuff.
