What’s your first modification going to be to your 4Runner when you get it? For me it will most likely be window tint. I live in Florida and this “mod” is a must! Bare minimum I will be doing the front two windows to match the rears. I think after that I may so a little bit larger/ more aggressive of a tire. Asside from that, I think I wanna push the new 4R to its limits in its stock form. Maybe just add an intake so I can hear all the turbo noises
