Tires Toyo or COMFORSER

Go with the Toyo T1-S tires they are unbelievable, more expenisve then the Potenzas, but also a better tire. Consumer Reports also rated them better then the Potenza for ultra high performance tires, so it's more then just my opinion.

Man these things blow the stock tires out of the water. I havent had a chance to really put them through their paces, but I did spend ~15 min messing around in an empty parking lot. I agree reguarding the ride/sound.

I am currently running them on my GLI on the street, and they are great tires! Very quiet, good ride, good dry grip, haven't had a chance to test them in rain yet. I would recommend them if you want an all-season UHP, that you can do the occasional autox on.

I've run Toyo RA-1s and thought they did a fine job, although I never did better than 2.1. With more launches under my belt, my Dunlop SP8000s have performed as well.

some people don't like them but I get good results with my Toyo FZ4 205-50-15.

With regard to tire pressures, btw. I'm running T1-S in a 245/45 16 size on my S6 wagon, with 36 pounds of pressure in each tire. I started out at 34, and picked it up to 36.
