Ok when you say "track" do you mean road/autox or drag?
As a STS driver the most dominate tires have been the Kumho MX and the Falken Azenis. Well the Azenis only come in a 225/45/17 and the MX come in a 245/40/17 for only $129. So if you are looking for a road/autox tire this is "the" tire. They work very well in both wet and dry. I would switch over if I had the money.
