I have S-03's on my 8 right now, and they're about warn out. I'm starting to look for replacements and I'm not finding the S-03's listed on Tire Rack anymore. Whats up with this? (They're still listed on Bridgestones website)

If these are discontinued, what would be a good replacement tire? I really loved the grip of the S-03's and definitely don't want to downgrade. The tread life was really good as well, much better then the original stock tires with a lot harder cornering.

Any suggestions would be appreciated..
