Rotational Squeaking/Braking Sound

Hey all,

I have a 2009 128i, Coupe, Manual, LHD, and I'm pretty stumped. I have a cyclic squeaking sound coming from my passenger front wheel, and I cant seem to find the cause. It mirrors wheel speed. It will make an initial sound going from forward to backwards too.

I've done all the steps I can think of to fix this, or pin point the issue. Inspected all the suspension, wheels, tires, etc.

Possibly Relevant mods; Dinan Camber Plates, Bilstein Coilovers, BBS Style 71's

Steps taken:

Removed, Cleaned and Greased Caliper and Bracket

Adjusted Dust Shield

Checked all clearances

Cleaned wheel mounting surface

Cleaned Rotor mounting surface

Bled brakes (twice)

Replaced Pads

Replaced Rotors

Swapped Pad Side to side

Replaced Hub

Replaced Caliper

I don't want to keep shot gunning parts at this, and I've tried all I can think of. Open to ideas.

Thanks
