are default car setting set to the real car as it is in it's given series like GT3,GTE. I have all assists turned off in settings. Am I turning off car settings like traction control that are actually used in the series. Just wondering as I'm driving around the new Nords and watching AI ride the curbs like they're flat, But if I even touch the curbs I'm backwards and riding the Armco.
No. TC and Abs is still on if the car has them in real life, and those can be adjusted in the garage menu.
You still need to assign keys/buttons to the ABS and TC. If you look at your setups, even the default setup, you will see options for changing the levels for TC and ABS for all the cars that allow such changes. So both ABS/TC for GT3(excluding the new GT3 Cup Porsche) and GTE cars have one of those options, Traction Control I think.
