I am currently running brakes from an AE111 corolla on my ae82, straight swap, bolt in drive away, car stops on a dime. Its an excellent upgrade.
I also sold last year a set of twin spot ae101 levin gtz calipers and rotors to a fella in sydney cause I couldn't afford to get 15's to fit the brakes under, they where slightly bigger than the ae111 rotors and needed just the littlest amount of machning to make them fit and the twin pot calipers would surely make it worth it.
Ae92 SX brakes are also bigger than the ae82twin cam ones (both front and rear) you'd need to get new mounts made up for the rear ones if you want to use them. I have a set of ae92 rears if you're interested.
