Grippier tires will tame the exuberance of this chassis. In return you will enjoy the fundamental precision Subaru designed in. Assuming you have a 2017 model with the sports option you have Subaru's idea of the best street setup you can get. After five model years Subaru has built the car they probably should've built first. Larger and wider wheels will sharpen turn in and likely make your car more responsive in transitions. Not so good in the wet or on snow but what you want on dry roads.
Toyota issued a set of lowering springs and uprated roll bars early on. All reports are these are a good addition, or the many equivalents from other makers. Toyota bought theirs in from Eibach, one of the biggest and best aftermarket makers.
Lowering the same by that much will improve handling but reduce suspension travel which may not be what you want if you experience rough roads. But, you give up the factory suspension which is now very good indeed.
No free lunch, just a set of trade offs. One modification at a time is a good practice. You stop when you think the car is perfect for you, or you run out of money....
