Re: AE86 Rear Brake Upgrade - Caliper & Discs?
Your in luck, I just took a bunch of different measurements of my rotors (Granted, they are aftermarket rotors. But they should be the same.)

Not measured: A, B, C, D, DD | G, H, I, J, K | O
Not listed on form: P, Q, W, X, Y, Z

E. Axle flange outside diameter:
139.0mm

F. Axle flange/hub center size
60mm

L. Brake rotor stud hole
14.65mm

M. Brake caliper bracket hole
10.15mm

N. PCD / bolt pattern
4x114.3mm / 4x4.5"
__________________________________

R. Same as 'E'

S. Brake caliper/bracket position.
S1

T. Brake Rotor/Hat overall height:
48mm

U. Rotor/Hat inner diameter:
139.7mm

V. Rotor/Hat Inside depth (calculated on 2 measurements above)
42.75mm

Check mark at bottom - Caliper is positioned 'Leading' of the rear axle.

Misc:
Brake pad contact surface/height (measured actual contact patch width on rotor):
30mm

Rotor Hat thickness @ axle flange:
5.25mm

Rotor/Hat outside diameter:
159mm

Rotor outside diameter:
231mm

Rotor thickness.
10.1-10.2mm

Quick tip: Rear rotors from a MA45/46/47 are a direct and almost identical swap to the AE86 rotors. But they are just over 1" in diameter bigger.
AE86 = 9 3/32" (231mm) - approx
MA45/MA46/MA47 = 10 5/32" (258mm) - approx
