I did my first AutoX too. Unfortunately, I got stuck with all-season tires. I did pretty well considering
I beat a supercharged BRZ, a 370z, a Mustang Cobra, and a couple WRXs. I also lost to a 97 Outback Sport, a Mazda 3, and almost a Scion XB.
If I had the stock tires I would've done much better. I'm trying to scrounge up a replacement wheel without spending a ton of $$$ so I can do better in August.
