Put the RB pistons/seals/boots to the test yesterday evening. Did one lapping session at the track. Braking is much smoother, predictable, and stronger throughout the session. No sign of fade. No sticky pistons or squeaking when I exited the track ...

It was a cold evening though, at around 10*C/50*F, so plenty of cool air directed to the brake rotor center via my custom ducts ...

I need to gravity bleed the calipers (did various combination and cycles of bleeds with Motive PB, and still not totally happy with brake pedal sinking when I get into ABS). I ordered Russell speed bleeder screws, and new brake fluid. Will install these and do a few more rounds of gravity bleeds as soon as I get a chance.

I will report back...
