Noise when turning?
 

Everytime I enter a sweeping turn, the rear (brakes?) sound like they are rubbing. Sounds like a squeeler tab on the brakes, high-pitched.

If I go into a right hand turn, the right rear makes the noise, if I go into a left hand turn, the left makes the noise. :(

I have iRotors and Hawk HPS pads, both almost brand new (few k miles on em).

Is there anything I can do?

Thanks!

There is probably a small amount of play in the C-clips on the diff. That is probably letting the axle shift towards the outside of the caliper and drag the pad just enough to make it chatter against the caliper. Those Hawk HPS pads have enough bite that it shouldn't take much contact to cause them to move against the caliper and squeak a little. I'm guessing that you're stuck with it.

See, we increase your cornering grip and now you have squeaking rear brakes.....Time to upgrade the brakes and make squeaking tires....:)
