Before I optimized my combination, I had Cordoba 11.75” front discs, Dr Diff/Cobra 11.7” rear discs but the caliper sizes were vastly different. Fronts were the 2.75” single piston design used from 1976 onward. The rears were 1.5” single piston. I was at a 3.3 to 1 ratio and while the car stopped well, the rears barely did anything. I swapped to 13” Cobra rotors and smaller front calipers along with a proper booster and now the car feels right. I can actually get the fronts to skid. The car stops better than newer cars I’ve driven.
