Exactly right.

However running 30 series front tires is kinda blah. But I am coming from a Land Rover Autobiography with air suspension and fat tires. It’s so quiet and smooth it makes the M4 feel like your riding over gravel to be honest. Some of us have been spoiled with the Autobiography’s.

M8 has double wishbone, while g8x uses McPherson struts up front. In theory that means g8x should have more spring travel, which gives it smoother ride, but less composure and control then m8. Unfortunately I haven’t driven M8 to confirm or deny this.

Also g8x has plastic wheel arches, I definitely can hear all the stones and rocks and other garbage that my tires pick up. Not sure if that’s the same for m8.

i have a feeling the Touring would have a much stiffer rear end than the sedan

Go drive one - there are plenty of preowned and new to test drive. I find it depends on the tires, the seats, and the road quality where you live.

I found the M3 comp x drive to have a stiff chassis but a compliant damper/spring setup when in comfort suspension/chassis mode. In my experience the non-comp (manual) M3 is about the same but a bit less taut of a chassis - could be the bucket seats or my imagination. In both comp and manual the M3 is very smooth.

Just as an example, we have speed humps in our neighborhood - in my Z4 I had to go over these at 8 mph to be comfortable, in the Tesla model Y at 10 mph, and in the M3 at 18 mph. This is the ultimate test for the suspension for rebound, spring, and dampening. And the M3 is on rails when in the curves in sport or sport+ chassis, so it’s the best of both worlds.
