G92 vs. 1LE rear brakes

Are the G92 and 1LE rear brakes the same? As far as I know the 1LE only adds better front brakes as far as braking equipment goes. Correct??

Re: G92 vs. 1LE rear brakes

G92 is AXLE REAR RATIO, PERFORMANCE, you must mean J65 brakes? J65s are delco moraine cast iron calipers front and rear, front 11" rotor. 89 up for the birds and 90 up for the camaros use the PBR rear calipers for the J65 brakes too, so the same as 1LE. 1LE has aluminum PBR calipers front and rear on a 12" front rotor and a modified spindle (no caliper mount on it, it's been cut off) 1LE rotors are different in offset too and use a larger outer wheel bearing. The rear PBR calipers are rear mount where the delco moraines are uber cheap front and rear mount, l&r are the same caliper. One is leading, the other trailing and it looks plain silly.

This is the earler J65 rear setup with the moraines.
