Chicago Airfield II
Time to start dominating Race Days below Battle Machine. Since you now have two Grip cars you should choose which one should be your backup. It's also a good moment to spend some cash on your rides - Engine, Suspension and Nitrous should be your main interests, but improving car's body can also probe useful. Be sure to invest some cash in your drag car and leave some money for the repairs.
Grip: Center Field Loop
Completely new track - if you aren't sure about your chances, take a practice run first. Only few of the turns require you to lose momentum, so don't overuse the brakes. Pay some attention to the map.
Grip Class: Airfield GP
Not much to say, since you already know the map from previous Race Days. Don't rush, as many of the turns require you to slow down. Quite easy.
1/4 Mile Drag: 1/4 Mile Drag Strip
Check previous Drag entries.
Time Attack: Center Field Club
You already know the track, and you need only one good lap, so stay focused - it shouldn't be difficult.
Time Attack: North Field
Acceleration is of the essence here, as you'll have to gain momentum quickly after losing it on some of the tracks hard turns.
