KE30 hubs with KE20 bearings at the front.
maybe KE30 axles with shaved ends for the back?

lop about 6mm off ke30 axles and they'll fit in. if you don't shorten them, they'll mushroom inside the spider gears and you won't be able to get them back out again
you'll need matching ke30 drum assemblies too, as the axle flanges are different between ke20 and ke30 axles
i believe you can also change over to larger ke55 drums if you so desire

i have ke55 brakes on my ke25 struts, the ke70 uses the same rotors and calipers
some ke70s have a wierd backing plate, some have one that will fit on a ke20. ke55 backing plates all fit on ke20. you'll need to drill and tap the ke25 struts to the same bolts as the ke55 struts (M10 coarse thread)
you can use the ke55/70 hubs, just with the ke25 inner bearing. there's about 1mm difference in the seals but it doesn't really matter
the difference is nice, but if you're making a bit of power you'll want better brakes. you can't just swap in other struts, you'll need to do steering knuckles and ball joints too

you don't need to modify the caliper mount if you use the proper one. besides which, that's illegal and dangerous
when i first did my swap, i noticed my brakes really sucked. make sure your drums are adjusted properly, if the shoes aren't set properly (and i suck at adjusting drums) then you'll have some sponginess
i'd recommend taking your car to a brake place and having all your stuff adjusted properly, and have them bleed all new fluid into your brake system
oh, and those ke55/70 girlock calipers use the same brake pads as the rear of a vn commodore (db1086 and db1088). you can't get performnce pads (such as bendix ultimates) for a corolla, but you can get them for commodore
