Hi mate i used the bracket supplied by craft differentials in sydney it cost me $120 for the 2, then all you need to do is machine down the end of the axle so the R31 rotor once you have drilled it out to five stud ,can then fit over the centre section that supports the middle of the brake rotor. If you get all your parts you'll see what you have to do. Also don't forget about hand Brake cables which need to be taken to a cable place that can modify your corolla ones with R31 ends to suit the caliper. These need to be measured properly as if you get it wrong they wont work properly. I'd get cable guy to measure them for you. ;) Hope this Helps
