Tips for getting around Martinsville.. You can go deeper as you get better, but to start, try and be on and off (or nearly off) the binders by the time you get to the concrete. A good starting point for getting -on- the brakes is where the asphalt changes color. Again, go deeper as you get comfortable. Enter the corners low (nearly touching the curb) then diamond the middle of the corner and exit low as well, nearly clipping the curb again. If you wrap the curb all the way through the corner, it'll eat your RF tire, if I recall correctly, and after some laps your lap time will suffer greatly.. Obviously if you're in a battle and side by side, you can't diamond the corners, but if you have clean race track, this will be the fastest and most consistent line.
