Front LT1 rotor size and or part number

2023 LT1 front drilled/slotted rotors wanted.
The caliper is the Brembo 4 piston with NO pins, it has hex screws. I'd like to do drilled and slotted rotors but can only find the rears. Chevy tells me the front is an 18" rotor with a part number of 13526439. Everywhere I look it says it's around 14" diameter. Has anyone found aftermarket rotors for the big LT1 fronts?
Any help would be appreciated.

I believe the LT1 has the 12.6" rotors that are common with the non-V8 upgrade Brembo brakes. The SS has 13.6" rotors for reference.

There are subtle dimensional differences between the base 12.6" rotor and the Brembo 12.6" rotor, so be aware of that too.

I have 2023 LT1 and am looking to do something with rear calipers. GM has an upgraded rear caliper but it doesnt have the park brake piston on them. I know rear brakes dont do alot but just doesnt look right with big brembos on the front. Got some caliper covers but not realy liking them.

Didnt mean to change subject to rears. I would like the drilled and slotted also for the front.
