Ride along for a very brisk 1:40 lap of Sonoma Raceway in my Ford Performance Mustang GT4+ by Multimatic. 
(note: the sound is a bit behind the video feed; watch the speedo for the real story. Because shakedown)

For reference, this lap was 3.5 seconds faster than the next-quickest car in the track day, would have qualified me in P2 in the Porsche Owners Club race that weekend, just behind a well-driven 911 GT3 Cup Car.

This run was in mid-morning on sticker tires, lap 3, temps in the high 70s.
