Basically the whole span from start of static friction, over dynamic friction until you completely loose control. English isn't my native language so ... The old Stock-cars, and also many other cars are basically a bit to easy to slide IMO, especially at high speed and high slip angles they are to easy to catch. It's a very subjective impression of course. I tested yesterday at new Loch Drummond track with road config (just changed steering ratio to 1:10 I think) and default setup.
