Ok, I replaced the rear rotors (brembo) and I still have that freaking chirp on the driver's side. The new rotor is wearing on the outer edge of the rotor face. I think my axle is bent (moser 31 spline). It's cutting into it like a lathe! Chirp goes away if I unload that side by turning right. Let me know if my suspicions are right. I'll **** a brick if it is bent.
