What kind of performance are you looking for? You can pick up some 235/40/17 Federal 595 RS-R for around $500.00. Awesome tires, wear like Dunlops. http://www.onlinetires.com/products...%2F40-17+federal+595+rs-r+racing+90w+bsw.html
Keep trying, they will get more. I placed an order and kept calling once a week. If you talk to them they will usually give an estimate on arrival dates. They may not have gotten stock yet this year.
I have some pretty new Dunlops for sale: http://mnsubaru.com/threads/dunlop-sp-sport-01-235-45-17-high-performance-summer-tires.48860/ Let me know if there's interest in these
Might be interested in selling my tires. They are 235/45/17 tires. I've only used for one summer. All are equal measurements. They're still mounted on my wheels at the moment. I'll get exact specs if you're serious?
