6 events may feel like a lot, but 6 years is more like it.
i bet if you put some of those faster drivers in your car and you drove theirs, you would still be in last. i'm not trying to discourage you, but i'm walking proof of this. and i'm sure others are as well.
buuuut if you want the best street tire for autocross get the RS3s, if you want the best race tire for autocross get the A6, simple.
