It's all accurate as far as I can tell.

I posted what the rear rotor diameter is on nabisco.

I wouldn't be suspicious. The SVX had the largest diameter front rotors of any Subaru up until the brembos. You should see the pads, not that it really depicts rotor size, but they're huge. The rear were the largest up until the 2 pots/BE/BH I forget which came first. The front thickness is huge too, 28mm, BL/BP size. And apparently the JDM spec SVX's had 290x18mm rear rotors, VENTED! Hell of a braking system.
