We have three questions here which aren't necessarily related.

TC, BA, and SA do affect performance, with TC being the biggest offender.

TC adjusts for skids, though I find that I tend to skid more with TC on, than off (though it has been a while since I used it). As it generally reduces power applied to spinning wheel, it will slow you down considerably.

BA Low can actually improve times if you aren't too familiar with the brake points on a track and a car combination. It is a learning tool though. Once you get a general sense of where to brake, turn it off and refine your brake points, because there are places you can brake earilier or later than where BA low will suggest. BA high will pretty much mimic the behavior of the bots, so that will definitely slow you down considerably and make it difficult to pass any of them.

SA is basically just there to enforce racing line, but it does a really poor job of it. It can also give you some bizarre behavior and fight you when you are trying to do one thing and the game thinks another is better. After turning all assists off, I used to use this for ovals, but I can do ovals without it for the most part now.

Steering Sensitivity is about attenuation. I once had a surgeon describe robotic assisted surgery to me, and this is how I think about the SS. The robot makes his movements more precise. If he moves his hand two centimeters, then the robot will only make a one centimeter movement. It is the same with SS. Set it to 0 and you have to give a greater steering input to get the same result as a higher setting, which means it increases your margin for error. There are times though when you want your SS to be higher. Performing donuts or skids in challenges come to mind, however if you have found a good line, the correct brake and acceleration points, then you aren't going to need very big movements in steering to begin with, so lower sensitivity means better attenuation.

The problem with the Apple update is likely how iOS 11.1 transmits the accelerometer/gyroscope data to apps, leading to unexpected behavior. This will require a patch to fix and can't really be addressed with anything that you do.
