Axle geometry Fall rear axle Comparison front motor/rear motor

Hello, my friend had her Citroen C3 perform an axle measurement last week and got a protocol. When I looked through the protocol, I had to be terrified to find out that she has the same crash values on the rear axle as I did in the 911. How can that be? Elfer=Heckmotor, rear drive C3=Frontmotor, front drive And both have a target value of 1°50 minutes on the rear axle. In the Porsche I can understand that… big heavy engine behind the rear axle …. if the rear tyres are not properly attached, the car slips away. But the C3 has a completely different axle load distribution. C3 approx. 65% front, 35% rear 911 approx. 35% front, 65% rear And yet both vehicles have comparable crash values on the rear axle. I don’t understand. Can anyone explain that to me? What would happen if you set a neutral crash on the rear axle at the C3 … so 0 degrees. n Axis should the effects be minimal?! Thank you and greetings
