AP racing caliper numbers

[alexk]

Hi guys,

I need your help with something.
I have found an option for AP racing front brake kit.
The caliper of this kit is the CP5555.

I saw on AP's website that this caliper needs aftermarket wheels, while the ones that can be fitted with the OEM wheels are the CP5575.

I have OEM wheels and I don't want to change them.
What is the case ? Will the CP5555 fit or not ?

Thank you please
