question about coilovers and tires

[Z-owned]

Alright thanks for any help on this i know absolutely nothing about suspension but i have been looking at redoing mine as it's starting to wear out. I have been researching and for a cheap route with quality I have been told this is the way to go link below

But then for a couple hundred more I could get these the "sport street" model.

So my question is which is better out of the two? I want the best handling possible for under $1k and also for the dumbest question when you put those on and lower the car am i going to have to change the tire on my rims to make them fit or can it be adjusted for what I have on it?

i would go with the coilovers. You shouldnt have to get different wheels and tires. You can get a spacer if you do start to rub.

Ya I was kind of leaning towards the coilovers as well as I hear people who have had both noticed a big difference for the better, however my car is my daily driver so i want to keep it somewhat comfertable.
