No way, leave the fogs. Are they painted amber yellow or are they the real deal. If they are true yellow fogs you could get some decent money for them. I just painted my clear fogs that yellow color. The clear fogs would prolly look better with the color of your car, but I say leave them. I wouldn't go bigger than 17's for wheel size. 18's are just to big for hatches inmy opinion. Lower the car before wheels would be a great mod. Good luck and the car is looking good.
Also taking the lense off the headlights and painting the housing a dark gray or black would be a good improvement also. Too much shiny chrome blinging out of there.
