From what i remember of SRF , 1 year and a half i´ve burned my PS3
, we can´t call this GT sport aid SRF.
SRF was a huge help that let you trash the car across any turn succession like the first 2 km of the nordschleife for example, not only limiting and assisting your drift but also your rear end under accel out corner even with a high LSD accel setting and extra grip everywhere.
This is not happening in GT sport. In my point of view this new help behavior work together with tire physics only.
It just stop the rear end at a certain angle of drift and kick it back inline. You can feel a bigger amount of rear grip entring to rescue you from a spin , or at least maintaining you in the pace of a pack if you´re racing.
We have now a GR3 Nordschleife event for the americas. Take a fast car like the GTR or BMW or any top car with extreme settings on this track, take flugplatz double right full gas.
After the first apex , to be fast there you need to open a bit your driving input after the little depression because at the landing there is a little compression that give you an excess of front grip , right in the middle of the double turn.
If you insist to give more wheel input there , you´ll feel your rear end going away very hard.
Any car in a normal game physics condition (of course with the extreme settings that the help allow to drive there) would spin immediately. Here is a great point to feel the help. It correct immediately your driving line and stop the rear drift after just a few degrees out of the line.
Excuse my english , sorry if i was not very clear in my report, but this is what i feel about this driving help.
