And loosly boltwd in place, not a bad compromise between the 6 piston vette calipers and the Z51 4 piston calipers. Id have to give my vote for the 2019 Z51/CT6 calipers and 13.5" C7 Z51 Rotors. The pricing wise, $300 for both complete calipers (bolts, pins, harware, old pads), $16 for new banjo bolts, $160 for rotors, and $80 for new pads. Had to buy new wheelhub bolts $20 for my build since i had C5 brackets with longer bolts on mine, So roughly $500 total for a large brake up grade.
