Yes....the recommended daily driver kit is the Z23.... https://www.powerstop.com/products/?recommended=true. The more aggressive kit is the Z26.
By the way.....you could have answered the question yourself by just going to the Power Stop website

Look in your glove box for the RPO sticker, and tell us if you have either Jl9, J55, J56 and ZR1 listed or not.
On the power stop kit, need to know the manufacturers number on the kit, since they make kits for the above brakes.
The JL9 is the smaller rotors for the base brake system, the J55 is the base car with Z51 option that has the larger rotors, but uses the same size brake pads as the JL9 calipers. The J56 is the GS/Z06 rotors sizes with the clam shell calipers, while the ZR1 is a strange duck code that list the rotors and calipers on it as the J55 brakes with ZR1 RPO, but Brembo clam shell calipers and the largest of carbon rotors isntead.
As for the kits, it will give you the correct kit (maybe) when you plug in the the subcontractor for your car,

And I say maybe, since glove box may show JL9 as the brakes, but someone changed out the brake brackets to use the larger Z51 rotors (j55) in the car isntead.
Or, could have pulled the stock calipers and rotors to use larger after markets. If you can post a photo of your front rotor and caliper with the tire still on, make short work of trying to figure out what size rotors are in play.
Front oem J55 rotors on base car with Z51 option J55 brakes.
JL9 will be slightly smaller rotors (more distance off the barrel of the rim),will not be drilled, but caliper will look the same..
