6 piston Brake upgrade

[andrewpeanut]

Hi all

could someone who has done this swap before help me confirm parts?

'15 Z06 W/O Carbon Ceramic Calipers
1722646
1722645


'15 ZL1 Backing Plates
20944532
20944531

'15 ZL1 Lines


Rotors
are off of 15 ZL1 or what year CTS-V?
I was guessing 15 but im just trying to be sure

and of course pads for a 15 Z06 to match


is there anything else im missing?

all input is gratefully appreciated.

I think you need the axle nuts and the caliper bolts as they are TTY bolts.

here is what i have so far, i don't know if this is 100% everything needed for front 6-pot conversion:


Mfg + Part Number Description

ACDelco 177-1146 passenger side rotor
ACDelco 177-1145 driver side rotor
ACDelco 172-2488 passenger caliper
ACDelco 172-2487 driver caliper
ACDelco 20944532 Driver Dust Plate (Backing Plate)
ACDelco 20944531 Passenger Dust Plate (Backing Plate)
ACDelco 18K2108X brake caliper hardware kit
Good ridge 12227 stainless brake lines (zl1 calipers)

I could see changing caliper mounting bolts

but theres no axle nut to change up front?

so that's ZL1 rotors and CTS-V(09-15) calipers? correct?

hardware kit ok makes sense
