as above we have tcs , jsut stopping wheel spin
esp tries to stabilise the car under hard braking , in the ice a few years ago we slammed my mates atra sri derv's brakes on to see how his would cope , as it started stepping out it kinda dragged it back straigh if that makes sense
where as mine just locked up and abs just tried to limit locking up put still kept sliding in the off directian at where my wheel started locking slightly off course
