if u want to get improve lighting in the new model A4s they have BI-XENON headlights which use HID lighting for both low and high beam but those headlights are very expensive, i say just replace ur halogen headlight bulbs with a HID kit, that will improve ur lighting, and HID kits actually use less electricty then regualr head lights, and i dont know of anyone actually putting HIDs on the high beam but u can try, but i say just replace them with HID look alike halogens

yea the standard A4 comes with 16 inch wheels, the sport package comes with 17s and 19s look great on our cars.
if u want to upgrade to 19s theres no addition work besides getting them balanced and alignment, u may need some hub rings for u wheels also, and i say stay aweay from chrome wheels
