Start in D3. Actully I was told to help your auto tranny last longer to always drive in D3 until around 50 and put in D4.

At the track I just held my brake down and held the gas at like 2000 RPM's. It actully improved my reaction time and I almost got a .500 . (I even screetched the tires)

But dont do neutral drops. It seems that it slows the car down even more.
