Took a video of one of my autocross runs today. Check it out:

Street tire setup of Nitto DR's and Pirelli P600 fronts was pretty decent. A little bit of push if I went in too hot, but I could kick the rear out when I wanted to ('course ~470 hp helps)

You can also hear the new sidepipes using the Classic Chambered Cobrapacks.
