Get some nice wheels and call it a day. Your car looks clean as is. You already have the sport bumper going and tint, no need to mess with a good thing. Rear splash guards (can't tell)?

 

OP, welcome to to the G community, nice find!

Like others said, grille is a must. You can just remove the lower ones and its an instant free upgrade. They should be clipped on, there are OEM grilles behind them.
I would also add some rear splash guards, they give the back a nice finished look.

BTW, who is the nekkid dude on the porch in the second pic?

 

I think those 15 hundred wheels looks nice already on there plus it has toyo tires that's in good condition I don't think I'm going to mess with them, right now my brake calipers are pink when I bought the car so I want to repaint it red black or red.. What do you guys think?

 

Unless they're a BBK, do not color the calipers...that goes for drum brakes too

 

if they were pink, he should change it lol
