Did the instructions mention anything about applying the springs to a brake caliper with 200k+ miles on it and how that brake dust buildup might effect the parts performance?

A test suggestion: Since the improvement if there is one will be too small to measure in FE and since ABA is a bit too tough, how about before and after video of the wheel spinning up on jack stands. Get the wheel to 15 or 20 MPH, hold it, let it glide to a stop. Video the wheel. See if the clips help the wheel spin even half a second longer.

Just a thought.

Good idea James, but I don't actually have a set of jack stands, just a beefy hydraulic jack and the crappy one that came with the car.

When I was putting the new brake pads on, I noticed that even pressing very lightly with one finger on the caliper greatly increased the resistance to spinning the wheel. Also, they are stronger than their appearance would suggest (definitely a lot more force than a bent paperclip would provide), though definitely less than I expected. I have no data yet, but if pressing lightly on the caliper has that effect, perhaps pushing outward lightly is all that's necessary.

@cbaber, I'm not sure if it's supposed to be this way but there's some resistance from the transmission when I attempt to spin the front wheels, so it's not easy to judge. When I do the rears it make be more telling. I'm still breaking in my brake pads anyway.
