Nice. With cars in motion, like birds in flight, you want to give the car room to drive into. Try to allow more room in front of the car than behind it. I shoot several Porsche events yearly and find that 1/100 to 1/160 work for me, depending on how close I am to the action. This one's at 1/125, f/13, ISO 100, D600, 70-200 2.8 VRII @ 160mm
