Brakes update after 2 full days on the street. Minor squeals during light braking at low speeds are starting to creep in. It's not all that bad though so far, not enough to make me want to swap in a street pad for regular use anyways.
I imagine it will be a while before I fully understand the squeal, but so far the evidence seems to point to the idea that it's very dependent on how you treat the brakes. Basically if you're light on them on the street like a normal driver, it seems to de-bed them a little (remove some of the good xfer layer) and make them noisy. Doing a light rebedding seems to quiet them down for a while (and by light, I mean really just 4-5 good hard stops from ~50-55mph down to 10mph, fairly closely spaced together).
As I've always done, I'm careful to time it out so that I can let off the brakes and roll the last foot or two to a stop without them, to avoid burning them into one spot on the rotor (with a little parking brake help when necc). That alone probably avoids a lot of rotor and pad problems for me.
Time will tell if I can sustain a pattern of occasional partial re-bedding to keep them relatively quiet on the street between track days, or if I'll eventually give up and use a street pad to avoid noise.
The braking performance is awesome though, they're very grabby
