Hi, I saw your post about the gen 5 z/28 giro disc conversion kit. I bought some silver ZL1 calipers from a fifth gen. I currently have the 6 piston 5th gen ZL1 set up. If I buy the conversion, would it fit these calipers? I believe they are from a base model 6th gen zl1 but I'm not certain. The rotor discs measure 15.4 inches. 390mm. $1,400 is a bit to spend but if I can make this set up work I'll buy once cry once. Thank you
