Came along this video on youtube:
It is a 50 min video where different cars drive over rollers, this time it is not a commercial but just normal people in Lithuania. It surprises me that most Subarus are not able to dive off the rollers with two side wheels on the ground. This most likely because most EU models have an open diff at the back. Actually most AWD cars have open rear diffs. However, at 4.25 an old audi quatro (Torsen awd system) also shows slip but then suddenly jumps over. I assume the driver uses the handbrake to send more power to the front.
Question:
With an open rear and front diff does using the handbrake to lock the rear and thus sending more power to the front help. And can it damage the brake system or center diff?
