The time trial is for a PSN trophy.
Brake Balance settings can be changed with a dual shock 3 by setting buttons for the "RA Controls" in the options menu.
My controls are:
L1/R1 for shifting
Analog sticks for gas/brakes/steering
R2 E-Brake
L2 Rear View
Square is RA menu
Dpad is RA controls
I used SRF because all it does is make the car faster artificially. It's a handicap for newbies, sure, but I just wanted to get the trophy and decided to use all available advantages.
Since learning about the RA controls, I never use ABS. I set the strength of the brakes to 2/2 for comforts/SH tires, 3/3 up to racing hards, and possibly 4/4 for up to racing softs. Keep in mind that when at x/x the brakes still work as though they have the default brake bias front/rear. More in front.
This knowledge should greatly help anyone who wants to gold challenges in GT5 with a dual shock 3 controller.
