This is what I'd love to know though. Naive tire physics for the BMW in question:

- RWD car
- Fairly even weight distribution
- Higher pressure in rear = smaller contact patch, less grip
- Lower pressure in front = larger contact patch, more grip

Doesn't that actually create more oversteer? Is this setup to make the car feel sportier? I can't wrap my head around it.

I would love a BMW engineer who knows exactly what this achieves to chime in, but I'm doubting we have one of those in the house.
