Audi: 99 A4Q performance parts

I just bought a 1999 A4 1.8Q with 35k miles on it. I am looking for some
good web sites or catalogs that can help me upgrade some of the parts and
increase the speed off the line. can anyone recommend some good sites with
performance parts for Audi's?

I am also having trouble find the CD changer cord in the trunk. Any ideas
where it might be hiding?

CD wire: compartment in trunk on left side where tool kit is located.
Should be a little door/panel about 12x18 inches. (30x45cm). The
wire/connector will probably have a foam wrap around it for
protection.
