Ok so we just installed TRD springs on the blue 2013 FR-S. Ride height change was -20 mm in front and -25 mm rear. Front camber went from -1 degree to -1.2 degrees (each side) and we have crash bolts installed. Rear camber went from -1.2 degrees to -1.8 degrees on each side.
But I do not have the best available camber gauge.
What a royal pain in the ass this was, I could not find a 17 mm spark-plug socket anywhere in the USA. Ended up using a short socket and pipe wrench or channel lock pliers on sockets to loosen / tighten the strut lock nuts. It's Miller time boys!
