I searched through and found some fairly solid information on swapping out rear drums for rear calipers (mainly by swapping axles), but I couldn't find too much on upgrading the front brakes. Would swapping to Z28 front brakes be possible with stock 16" rims? Would there be any noticable difference in braking? I'm assuming the year would have to be different, as Napa has the same part number for calipers regardless of "Base" or "Z28" parameter, and with it would have to be the knuckles for holding it all. Has anyone done something like this or have any info on it?
