Car is back together and ready for the last event for a few months. The 12mm bolts in the top of the strut seem to allow for a rough -5.5* camber, I dialed it back to about -4.75* via the camber plates for now and I'll validate with the pyrometer.
Replaced the stock rear 14mm bar with a Mann Engineering I bought from the previous owner (MobiusTFS) of my Hyperblue, he found it wouldn't fit his second gen BRZ, unfortunately.
I did some rough measuring and came up with something like:
Max stiff - ~82lbin
Mid matching holes- ~67lbin
Full soft - ~51lbin
I've seen varying numbers from other people, so who knows what is actually correct. I put it in the middle for now, which I think is something like half? the rate of the stock 14mm.
