Under braking in some corners if loose the back of the car and it makes me spin.....what parameters can I adjust in setup to avoid that?
This is usually your first action when the car breaks out under braking.Try more brake bias on the front of the car.
Sorry
It was with the WTTC 2014 cars.... so front wheel driven cars?
brake bias was already 62/48 something like that
I was thinking something with the ARB, spring, etc... but have no idea what does what
Or even how to use it to your advantage.Left foot braking can usually help - also being aware of the symptoms of lift-off oversteer and how to avoid it.
