I dont see anything that hasnt been in the older installments for the game. Except maybe torque distribution. I dont remember.smellati

ah well i havnt really played the others, and i've heard theres no preformance tuning, i just thought i would try to be helpful lol :P, but oh well

Now, before you get mad at me and say "This is old news," I want to say that I dont know if its old or not, but I do want to share it with you.

In GT5 you will be able to adjust the following:

Power,Weight
Tires
Aerodynamics
Ride Height
Spring Rate
Damper
Toe Angle
Camber Angle
Brake Balance
Traction Control
Max Turning Angle
ABS
F/R Torque Distribution
Gear Ratio
