I figure I might as well make my first post in an autocross thread!
I ran my '13 WRX at the Bay State Corvette Club event a few weeks ago where it conveniently rained all day. I had signed up like a month prior to the event with the WRX because I wanted to try it out (I normally run a Miata), and the fact that it rained all day was perfect. I ended up with the 4th or 5th fastest raw time, 2nd fastest on street tires. The car blew my mind...totally stock.
