It's debatable. It's a love/hate relationship with the vertical screen. I really like how it looks when the car is off, but its total function is hiliarious. So far, these patches have improved the touch screen at least. I prefer the sound system, I want to say it's a package with the vertical screen. It's a noticable improvement over the stock sound. Being that the car was MSRP $63k, if I got a 8" touch screen for that dough, I'd be looking elsewhere. I bought mine used though. For reference, I paid $35k financed (no money down) just a trade-in that had a great LTV, for 36k miles on mine.
The stock brakes/rotors on the 21s that I have I don't mind, at some point I'll upgrade them for sure. They look bad-ass with the black wheels. You can actually put on 20" tires, as well as move down to 18" wheels with a different size as well (that's what the LEO do). My winter set is 18" interceptor wheels w/ tires. Works as intended.
As the other person mention, the massaging seats are really nice, but I do feel like they don't go as high (I'm 6'1"), but still a nice function for longer trips. I would grab the street pck and the tech pack as you mentioned. Regardless of the vertical screen, It's totally worth the upgrade in terms of sound & other features.
