In 2011 my wife changed from 2000 Maxima(Koni yellow dampers+H&R springs) to 2010 M35X(stock). She complained the new M35X was unstable and difficult to drive. I think more sticky tires should not be very useful for my wife as she doesn't drive that fast. However, she could feel much more confident on a stiffer suspension even though she just does grocery shopping... 😂
