I have looked into MANY options both front and rear, and if you want simplicity and you are on a budget, then go with this:
Front brakes:
To go with Corona brakes, you will need:
Corona XT130 or RT132 struts, complete with discs and calipers.
Corona XT130, RT132 or AE86 (and maybe some others) steering knuckles
AE86 springs, preferably lowered (KTFL33 from King Springs)
AE86 top spring hat
KE30 or KE55 strut top
If it is easier (it was for me) you can also use the Corona control arms. That way you don't need to disassemble the steering knuckle from the control arm which can sometimes be a pain if you don't have the right tools.
A combination of all of those things will bolt straight into your car. You will get some positive camber on the front, this can be fixed by Pedders. You can get longer control arms and/or adjustable strut tops, but that becomes complicated and expensive. If you are in Brisbane call Brian at Pedders Geebung (after you have put it all in your car), tell him you need to have your camber corrected, and he will fix you up. If he doesn't know what you're talking about, tell him you need the him to set up your car like Fook's red Corolla.
Rear brakes:
KE55 diff will bolt into your KE30, along with the bigger drums. In fact, I have one for sale if you are interested. You will need a KE55 tailshaft. I might have a spare one of these.
Anything else becomes complicated and expensive.
