Obviously, it also affects traction depending on the conditions of the road. Beyond that, the Mazda 3 is a lighter car with the same tires, and a higher air pressure is recommended from the factory. The interesting point here is that in reviews, the Mazda couldn't hold the skidpad or stop as well as the Subaru, and I wonder if it has to do with the car or with the tire pressure, and how they were tested. The suspension is indeed completely different so that at least is a good point against overinflating, but at the same time I can't imagine it would wear that badly on the shocks would it?
The Mazda 3 handles better stock than the impreza does, the higher pressure is probably why the skidpad wasn't as good
