That's a clean looking 4 door. You asked for suggestions/recommendations so here goes. Don't go 18's. 17's are as big as you ever want to go. Anything larger than that your car get's put in a different class called "show" right now it looks "go" As for the flaming seatbelt cushions? I personally don't rock those but if they were swapped out to maybe Honda or Acura pads that would be acceptable.
