Zavage, I'm not sure if you can order based on GM part numbers, but here they are for the stock 1SS/2SS:
Front rotor: 13528522
Rear rotor: 13592623
Front pad kit: 84732488
Rear pad kit: 84732503
The online catalog is indeed confusing; it's showing you all the choices for trim-specific brake configurations (LT, LT1, SS, SS 1LE, ZL1, ZL1 1LE), and the ones you may be interested in for your car (SS, SS1LE, ZL1, ZL1 1LE) are theoretically interchangeable. However, if you want to upgrade from your J6G brake system, you'll need the correct calipers, brake hoses, shields and hardware as well. |
J6G is 339 mm on the rear and 345 upfront. In 2023 I replaced the brakes on my 2016 2SS by myself.
Front: 13528522
Rear: 85589611
The brake pad part numbers are correct.
