The suggestions in this thread definitely help, for sure. It's funny, though, when I set AI to 10 and choose a group b car, stock, the competition cars usually consist of two AWD cars, with at least one of them another group b car, then always, one RWD car. Of course the RWD car can't compete and in a five lap race I usually lap it, not matter what the car may be. I have noticed that along with adding weight, changing the torque diff to 30/70, thus reducing grip on snow and gravel, makes a race more enjoyable/difficult. Not that intentionally choosing a bad tune for the car is enjoyable, there is a fine line in tuning that allows you to still toss the car around, have fun, and run a little slower to make races more interesting.
