User blog comment:ME7/The Problem With Assists and Tilt A/@comment-4939977-20180408134330/@comment-26388545-20180410013145

I ran the exact setup you run for my first 18 months in this game. I explained in the blog exactly why you're braking too late, it's what the assists have taught you. I too used to slide all over like I was on ice when I turned off assists.

There's nothing wrong with running those assist. However you will spend more in SE vs a no-assist drivers. I also doubt group B WTTT times are possible that way, even in a fully upgraded car. So less coming in and more  being spent.
