For once and for all - ZL1 brake pads recap
 

There are dozens of threads with correct and incorrect pads information. So far I gathered that the FRONT pad size is 1835 or 1395 ( 189.7 mm wide / 96.6 mm tall).
Which pads did you confirm that fit, both track and daily driver pads. Please share name and model number (rear pads are easier to find).

I’ll start:
Raybestos ST43/ST41 size 1835 available at Portrefield (they cut them)
Power Stop Z26-1835.
Stock GM 23399101

I’m under the impression that pads for the 2016 CTSV are identical.

Power Stop 1053/1835. Have them on mine. Exact size of the factory ones I took off. 3500 miles or so with no issues and no dust! And CTS-V are the same:thumb:

I agree, yet which pads are available?

Do ZL1 and SS1LE models share the same size?

EDIT:
No. They have different pads
See pic

No. SS 1LE calipers/pads/rotors are smaller than ZL1

Guessing you misread his question. ZL1 and ZL1 1LE are the same, just different color calipers. SS 1LE has smaller calipers/pads/rotors.

Ah, thank you

KNS Brakes has a lot available for track pads.

I need to give them a call. They have inconsistencies in their website. 2016
CTS-V show different options than 2017 ZL1. Also their website does not share spesific model numbers so I could confirm they have the correct size.

Ooops. ZL1 and ZL1 1LE is the same lad but different caliper color

Following!

2016 CTSV shows part # 23399101, which is the same # as the ZL1.

A guy I work with has one as a daily driver. The brakes are the same as the ZL1.

I installed 23399101, and they were IDENTICAL to the stock ZL1 pads.
