[GP20]

I have a 2019 4GTS with Sport-PASM and also an 2016 F80 as my daily driver. Stock to stock, to me the 911 and the M3 are just about the same in ride comfort. Going over ripple roads, I feel like the 911's electronic dampers control better and react more quickly.

Search for the DSV V3 controller. With DSC V3, in normal mode, it's more comfortable than stock but also has less body roll compared to stock. In this mode, ride is more compliant and more comfortable than my F80. With the suspension in sport mode (GT3 Touring mode), it's on a whole other level and ready for tracks.

Handling wise, the 2 are not even close. The 991 is a proper sports car (relative to the M3, that is; I'm sure many 993/997 owners will say the 991 is just a grand tourer). The M3 feels like a large, heavy, quiet, overall comfortable and sporty sedan with lots of body roll. The 911 even with the twin turbos sounds better. Both PDK/7sp manual are better than BMW's DCT/6-spd. Build/material quality and attention to details? BMW just doesn't compare to Porsche. But the two cars aren't exactly in the same price range.
