It is not just only stiffer, i feel it is just better calibrated.

I think this is not exclusive to 4 series. I know C class coupe drives somewhat differently than sedan as well... and G37/Q60 Coupe vs Q50/G37 sedan.

I thought 4 series suspension was too stiff after having it for a while....it turned out that runflat really messed up the ride.

Now 4 series with proper summer tires = stiff without being too stiff because of the runflat.

When i had my F30 and change from RFT to summer, the car handled much better but it also felt even softer than with RFT at the same time because of the sidewall.
