i have a 1998 audi a6 2.8 its racing green and i was wondering what color 19" wheels should i get? all black,black with chrome lip,silver,or chrome?

im turning it into the sporty look im gonna remove the truck badges that say a6 and 2.8 and smoke the tailights out

and add 2 sporty mufflers on back like these:



and get this badgeless grille in front what do u think of this grille?

 

Any of the wheel styles you mentioned would look good, debadgeing is fine too, but, dual, dual exhaust, that is just not nice looking at all, and please don't slap on some cheap axle back that is gonna sound like a fart can.

I usually don't like the idea of people changing out the grill, but the all black look here is pretty clean, just be sure to black out the trim around the door and lining the trunk and under the headlights, it would look weird if you had chrome in those places only imo.

 

Personal opinion - if you do black or gunmetal wheels, get them with a polished lip - it makes them stand out more, and won't look like you're on steelies when you're driving. The rest of your ideas are spot-on, and the grille looks great. On my own car, I'd do a muffler setup other than the DTM style you showed, but that's purely personal preference. Single ovals (not melon-launcher sized though) would look good. You could also do the following:

window tint
RS6 door mirrors (chrome or titanium finish)
lowered suspension
painted lower trim (if not already body color)
