Why are many people using aggressive engine braking to help slow the car down? If the brakes are powerful enough then it's the grip of the tires which decides how quickly you can slow the car down. And shifting down gears aggressively can't magically give you any extra grip can it?
Even the bible (Speed Secrets by Ross Bentley) says that the engine is designed to make the car go faster, not slower

Oh btw.. Hi all. I'm quite new to LFS. Well, actually I've had the license for years but I've never quite liked this sim...until now. Suddenly I've started to like this sim much more than other racing sims.
