The Porsche nose dives. I’ll wager $1MM on that, if you’ve got it. 1 cm and I win.
Not sure what $1 MM means. But do you have it? Show us your assets.
Nose dive depends on where the CG (center of gravity) is compared to the center of rotation of the wheels. If the CG is exactly even with the wheel centers, then there can be no nose dive -- common physics. If the CG is below the wheel centers, the front would actually rise (what do you call reverse nose dive?) It is almost impossible to build a car with the CG below the wheel centers -- formula 1 cars?
The Porsche CG is much lower than most cars (depends on the model), thus suspension compression from the front wheels is less than other cars. For my particular Porsche, 914-6, under hard braking, the rear also lowers, about the same as the compression of the front suspension, thus the car body stays relatively level, but lower.
I'm not quite sure how you would measure suspension travel in a dynamic situation. How would you do it?
