Excluding aero, and assuming no elevation changes, the sum of vertical loads are always mass x gravity. However, the lateral loads are different and using weight instead of load contributes to confusion in the long run.

When a 911 lifts the inside front tire in the air, the outside front suspension is still resisting roll. If you go faster the car will roll more and the outside front suspension will compress more. The roll center does not all of sudden magically move over the outside front tire when the inside front tire comes off the ground.

My race cars lifts the the inside front tire off the ground just a bit going through turn 3a at Sears point. The only reason I know that is that I have seen photos showing it. The handling of the car feels no different at that point. The cars does not change all of sudden when the tire is in the air. If it did, I would spin off the road as I am near the lateral limits of the car at that point. It does not have an increase in roll so the front outside suspension is still resisting all the roll it was resisting before the front inside tire went in the air.....
