I just had a Stoptech 332mm kit installed this week on my B5 S4. I'm running the Axxis Ultimates that came w/ the kit and Ferodo DS2500's on the rear. I am getting an odd noise from the driver's side front area during acceleration and coast....but the noise instantly goes away when the brake pedal is depressed.

You can hear a rotational quality to the squeaking noise. As you drive faster the noise increases in frequency. Any ideas what could be going on here?

nto terribly unusual in any brake

we cant tell you vai the internet.
