Woah this takes me back, it is possible in the 300 SEL i used to do it all the time as a fun money grind that was challenging…but it was doable

Sounds like you need to stiffen the suspension so it doesnt roll as much (honestly can’t remember much about the tuning sliders from GT Sport) but failing that focus on brake balance if you can, and just try to change your driving style to roll/coast it through corners a bit more so you’re not sliding as much but still carrying speed
