So I took the car to my favorite SVX Master Tech at my dealer. If anyone could find it, he could. He took it for a test drive, came back to the shop and knew what the problem was.

It was a shield problem, but it was not bent. He showed me that the brake shields were not one piece of metal, but were made up of multiple plys. Age, moisture, etc. cause these to either swell, separate or warp. He also found a slightly raised are on the back of the Raceconcepts rotors, at the inner edge of the disk itself. He showed me the burnished marks on the back of the rotor AND the small area where the warped dust shield was rubbing. This raised edge contacted the warped brake shield at one point, about 1.5" in length, producing that sound.

He used a ball peen hammer and reformed the dust shield to give it the clearance from the rotor it originally had. He also ground down the raised lip on the inner edge of the back of the rotor. Reassembled everything. Noise completely gone!

If you pull off the back rotors, you should see the rub marks on the shield and/or the rotor. This is a fairly easy fix.

Thanks ill check that out
