Williams Grove is a very tough track. Once it gets slick it can be hard to keep the car underneath you down the straightaways. If it begins to get loose on you on the straights, lift of the gas a little bit and try to make smooth turns with the wheel, don't be throwing the wheel back and forth trying to catch the car. Try to keep the car from sliding in the turns. If you can keep the car from sliding you will be much faster (sliding is different from drifting. Drifting is the back two wheels are not travailing in the straight line that they are pointed in. Sliding is when all four wheels are not going "forward") Its a hard concept to grab but once you do it will help tremendously.
