Any tips to avoid completely uncontrollable vehicle behavior when using handbrake?

[Renato404]

I don't want to use vehicle assists script, because its not realistic way to do it. Will good wheel friction setup solve that, Or is it completely unavoidable?

Unfortunately the assist script is pretty much required for control when using the handbrake. You may be able to achieve sufficient control with enough tweaks to wheel friction, but it would be very difficult.
