Okay have to say if you are competitive should be able to filter results so just shows people not using SRF only.
Doesn't bother me I just don't use it get gold & call it a day as time trialling doesn't really interest me.
However with the patch letting you use it on the Karts thought I would try the GT arena shifter race with it on as for me that was the hardest race in the game.
Holly Cow what a difference, I then tried a couple of cars with it switched on as back to back comparison.
There isn't one its an entirely different car, helps a bit with traction out of slow corners but long high speed sweepers is where it really shows. You can actually drive quite different lines in some cases & shave massive times off your lap times if you adapt your driving style.
I am now tempted to try Goodwood in arcade mode without SRF to see what its actually like.
