Hey Monkey,
I think the link to that post was probably meant as a reference for you, as opposed to a definative answer.
Going on ideas from it, you could replace the front bumper with something like this...
or this...
both of which are easily found on ebay.
The second option, also found in the other post, would be to make a quick-fix yourself with some chrome detailing strips. Meh.
I'm pretty sure that there's not a 'kit' to convert the grille as for the 8P, but you could certainly ask Audi if they have a solution, or do a bit of research into any other options (again like the other post, German companies are probably the best bet)
I hope that helps you on your way, and maybe lowers your thirst for
bold text when people don't tell you what you wanna hear!
