These are the default controls for the game, they can be changed in the main
menu

D-Pad/Left Stick - Steering and Pitch
Triangle - Change View
Circle - Absorb Weapon
Square - Fire Weapon
Cross - Accelerate
L1 - Rear View
L2 - Enable Voice Chat
R1 - Left Airbrake/Sideshift
R2 - Right Airbrake/Sideshift

huh? are you sure?
i use default controls
square : absorb
circle : change view
triangle : maybe that voice thing
R1 : fire.
L1 : rear view
L2 : left ab
R2 : right ab.

what happened to you to write R1/R2 for airbrakes?

also : the % sensivity for airbrakes/steering section will help me.
