I view the PS4S as a straight upgrade. Grip, response, road noise, wet performance.
The main downside to me is that the factory spring rates clearly weren't designed for that amount of grip. Last summer on stock springs I could easily put the car on the bump stops in corners.
The car still handled great, but it obviously felt different. Pros/cons.
I wasn't a fan of how it felt. Since adding RCE yellows and camber bolts the suspension feels way happier dealing with the extra grip.
Primacys are a ton of fun on the street. So grip limit is so approachable, you get chirps and squeals before you get near the limit. Really just depends on how you like to drive...

This is helpful to hear your feedback on the impact to the stock suspension after adding more grip. It'll be something I'll look out for when I swap to something like the RT660's with stock suspension and stock wheels.
Everything is connected after-all. Brakes will be the next area of focus.
