I have an 03' A4 3.0 sliver and like most of those cars no sport kit but it has the black body kit I was wondering if that I could just get that part painted like the whole kit instead of buying a new body kit any one that can help me or show me what it might look like thanks guys.

 

that's called painting your lowers. Check DIY on this and other audi sites and you will find step by step instructions for that. And it looks much better. I did mine last weekend. best visual mod for the money.
