Ended up ordering RC6E pads at all four corners for the first experiment with the new brakes setup (because other CL compounds had to be ordered and would take forever), hopefully they arrive today. They're not super-grabby, so even if the lack of F<->R bite differential puts me back in ice-mode a little, I'm sure I can drive through it and/or tune it out via tire pressure and rear sway.
Also, I've got more new toys stacking up in the garage. Picked up a set of JRZ RS1 from Forged, and they look amazing. This and the APR brake setup are both in line with my new theme of "For a given chunk of cash, spend it on a lesser-featured product from a very high quality mfg, instead of a maximally-featured item from a lesser known mfg". They look pretty amazing so far on build quality, and I expect they'll do well on the car once I put them on. I'll probably stick them on the car and play with ride height today, but alignment and corner balance will have to wait a week while I'm out of town all next week. Any general advice on getting my initial ride height set up quickly (which I want close to stock, or maybe 1/2" lower) with this style of shock (helper springs, no adjustable shock body length) other than "guess at where to set the spring seat, set the car down, measure, iterate?" Is a "normal" setting on these kinds of shocks usually with the helper mostly compressed, half-compressed, or "as close to zero preload as possible, but just a little tension to keep things from bouncing off the mounts"?
Anyways, pic with the springs installed, still sitting in a box:
