Tough question to answer. I mean theoretically no, tires are tires and that's it. The body roll itself is not that terrible of a dynamic when talking in terms of total grip. But the bouncy trouncy-ness in my opinion is a very bad dynamic that causes the driver to pause and correct things that don't need to be corrected based on "feel". The body wavering around is also going to cause some loss in grip due to load transfers and just driver uneasiness/unsettling the car.

At the same time a car that is "rolling" over meaning that it has rolled too far, and it is causing some type of camber or roll moment problem, is obviously not acceptable either and needs a sway to tame it. The OEM suspension on this car hits that point quite easily. I can tell you that I could roll this car's front suspension over by probably my 5th track day. Mainly through any type of mid speed esses. Stiffer springs aren't going to help that if the car "falls" off from body roll. There's a point where roll is acceptable vs. losing a little bit of overall theoretical grip in order to not have the car feeling like I'm on a raft.
