now hear me out...stock front yaris rotors put on the rear using XB rear calipers..i belive i could keep my 14inch aluminum wheels..the XB rear calipers solve the E-brake issue without the need for a drum hat rotor....tho i suspect id need an adapter mounting plate similar to yours but 1/4 inch of more offset in the rear of a stock yaris drum beam would square up the wheelbase nicely

If you didn't know, the front wheels' track are wider than the rear by 10mm (5mm on each side), adding the 1/4 inch plate will make the rear 2mm wider than the front (1mm on each side).

How would the xB's rear caliper mount on the rear axle frame? Or are you swapping out the axle frames?
