Porsche 991 GTS drives M3 off the track at Buttonwillow.

Context; This is my first session of the day in the GTS, but the second session in Orange Group at speedventures. I'm coming up to speed. The video covers the 2nd and 3rd 'hot' lap. He obviously should have let me pass instead of racing me. My fast lap of the day was 1:59.73
