Thanks for your responses, they are appreciated!!!
Yes, after I uploaded to my computer, I could see some 'grain', so I knew I would need to drop the ISO. The day started out very overcast, so I didn't put my polarizer on. I should have taken the time to put it on after the sun came out :(!
It seemed like I was shooting constantly, throughout the day...quite a few misses, but a fair number of keepers. Hopefully, next year will be even better!
I shoot sports also, in many instances I have to shoot thru either a chain link fence, especially to get shots of the pitcher delivering the ball, the famous or infamous "bat on the ball". I shoot those shots primarily shot with a Canon 70-200 2.8 lens. I press the lens against the fence and find a spot inside that link to focus and and take the shots. Chain link of wired fencing is far more difficult to make this work vs some of the new non metal netting. I doubt you will find anything in use as a fence or barrier in auto racing other than real wired fencing.
Panning might be a great choice if you can focus and and get the focus to lock, the problem is panning thru the fence and links might blur the individual car you wish to capture.
You can also adjust you f stop to determine your the distances of the car your wish to shoot, the location you are allowed to shoot from.
In years past prime shooting for baseball was and is of course town the first and third baselines. I shoot high school baseball now and with metal bats in play and most of the pitchers who throw in the high seventies to mid eighties the speed that ball leaves the bat is blazing. So I have found that shooting thru the net at the backstop is easier than having an additional worry, being struck by a foul ball. So I move to the dug out to capture the batter, the pitcher side view, and of course the runners on the bases.
You also might attempt to move up higher to obtain a shot over the fence, you might get a far clearer shot and be able to pan a specific car and driver.
I you shoot in the AV mode, and increase your ISO until you can capture shots at no less than 1/500 if the cars are moving, higher if the shooting conditions will allow you to increase the ISO and and shutter speed without introducing noise. When you view the photos you don't have to dull them by using noise reduction software, so that the cars appear to look like the cars are Lego cars.
Here is a You Tibe vid by that might give you some additional tips on panning to get additional movement in your photos
