SHORT CUTS
Redrock Ridge (forward, non-mirrored):-  About half way into a lap, you'll have to make a difficult left hairpin turn. There is an alternative left turn immediately before that hairpin turn.

Atlantica (forward, non-mirrored):-  After driving past that "Electronic Arts" landmark (at roughly half way into a lap), take the left path, then right. You'll immediately see a shortcut entrance in the right wall. Upon exiting the shortcut, you'll need to turn right.

Rocky Pass (forward, non-mirrored):-  Where you see the falling-rock road sign, right past that sign, there is a small and short cave tunnel off-road to you right. Driving through it instead of making that sharp right turn on the road will save you some time.

Country Woods (backward, non-mirrored):-  There is one difficult left hairpin turn AFTER all those 90 degrees sharp turns (at about half way into a lap). Instead of making that hairpin turn, do this: A few seconds before approaching that hairpin turn, you can make a sharp left turn (with the help of your handbrake) and drop to the lower level. While still in the mid-air, continuously press that L1 reset button. You'll immediately recover from that crash landing and "skip" that hairpin turn. This saves you at least 3 seconds. One other trick on this track: there is one big and high jump at the beginning of this backward track (your car hitting the roof of the tunnel). Once landed, keep straight and accelerate all the way till you hit hard at the wall. When you crash, immediately press the L1 reset button to continue. This way you don't have slow down to make that 90 degree turn and can easily gain 2+ seconds.

Aquatica (forward, non-mirrored):-  After the initially left, right, right, right turns, now during the next long and gradual left turn, there is a shortcut entrance in the right wall. Upon exiting the shortcut, turn right.

Empire City (forward, non-mirrored):
a) There are light poles on your LEFT side when you just pass the start/finish line. Immediately before the 4th light pole, you'll find a shortcut entrance. After exiting the shortcut, go STRAIGHT. There is a wall in front of you but a little bit to your left is another shortcut entrance. Upon exiting this shortcut, turn right.
b) Immediately after the second SET of concrete pillars (when near the end of a lap), you will easily see a "fake wall" on your right side. Drive through it and you'll drop to the lower level. This saves you 2 to 3 seconds.
