I got it for you!
Falken Azenis RT-215. 205/55R16 from discounttiredirect.com is $85 each right now, with free shipping! Incredible crisp handling makes up for the tall sidewall, and they're a very wide 205. Not the best in torrential rain at high speeds, but not dangerous either, from what I hear - no personal experieince, but lots of people on the SCCAforums.com can help you out if you're worried. I wouldn't imagine you see a ton of rain in Cali anyway. These are much stickier and better handling than the KDWs or even KDW-2/S0-3, but may wear a little quicker. And cheap to boot! They are low in stock, closing them out, so you might want to bite now. So if you want to feel like you're driving a race car everyday...
