Not a GS, but 2:00 to 2:55 of this video kind of supplements flipside's comments.

ok well the 2006 awd gs 300 did'nt have the trac or vsc button so I guess the 350 does..what does this give you other than trac off allows you the slide around which is why the awd (at least the 06 ) did'nt have one cause that would negate the purpose of awd?? As far as vsc not sure

 

torque brake

 

what is torque brake and how do u do it

 

Although not recommended due to stress on the motor/tranny/etc

Say you're at a red light about to turn green, left foot on brake pedal holding it down firmly, use right foot and give it a bit of gas, car will want to go forward but hold it in place with brakes. When the light turns green, release brake pedal and get on the throttle. Car will lunge forward bit faster due to being in a higher RPM. only do this as minimal as u can if ever.

hope that made sense. you can look it up on google.

 

and if you do that, don't rev it to high rpm, coz' it all depends on the traction of the rear wheels
