Yup, I got about 20 runs in this year on it here in Sacramento before the season ended. I did pretty well in Street Tire class as well as ES where I actually won a couple races against a Saturn and a Civic Si. The last race of our season out here is an Enduro where you do five laps through the course and top three places tophy (I got third on that one because of my inexperience autocrossing, not because of the car). The day before that I was in second place I just went to easy on the first laps and it cost me a couple seconds. I got beat by the Saturn guy(an experienced autocrosser) and a Celica GT(very experienced autocrosser). But the car performs very well in the autocross arena and I expect to be at the top of the heap next season as my skills increase. A lot of autocrossing is the driver not the car which is why it is so fun! I'm actually considering moving to STS because of my MHP CAI, but the stock guys here don't seem to care about it, they think of it like a high performance air filter. I'm pretty sure on a National level that wouldn't fly.
Cool to see other autocrossers I encourage everyone to try it as it can be addictive fun and is the closest thing to racing you can get without putting your car in any real danger and not costing you an arm and a leg.
