@dlearl476 The 195s are in stock at Tire Rack, looks like they have 9 on hand. The 185s are still backordered, with an 11/30 arrival date. I don't know how many they are getting but the 1st 8x come to my shop. :-)
As for other 15" tires, I'm a huge fan of the new CN36s also. Since they are a "Porsche Dealer Only" tire, I'm not sure if they show on Tire Rack's site, but Stoddards is buying them from a Porsche dealer and remarketing them, plus I can get them for new builds. I've used them on a few cars to date and they handle VERY well...
