[s-cars] Front brake upgrade questions

[RM]

I know this has been covered to death, but unforunately I do not have the 
time to read my digests or archive them. Simple questions....

It's time to replace the brake pads and rotors on my 94 UrS4. I know the 
fronts are upgradable to bigger units, but this car is not a track car nor 
do i drive it hard. I'm leaning towards good Brembo rotors and EBC green 
stuffs, or any other premium stock sized parts. In short can anyone describe 
the parts needed to upgrade to larger units and aprox. costs?? More 
importantly, what make, model and year do the upgraded calipers/holders do 
they come from?! I have access to allot of junk yard parts.
Last question, will stock sized premium components work noticably better 
than originals??

TIA!!!
