drive immediately to Qualcomm Stadium for some Autocross and report back on your results!
That's what my fellow p-club driver did. Temporary tags were still on that GT3 when he brought directly to the autocross. Here's a pic with Toyo RA-1's glad I followed suit. The tires are fantastic. Insane bite and great for daily use.
This particular photo is from one of 6 clubs in our area, they love open courses!
check this out for your area.
