Default 92' base C4 Rear caliper

Can some one explain how to determine if I have J55 brake option or at least what is the difference with others. I am 3 months into this new toy and have the red books but can't find J55.

The best way to find out if you have that option is to look under your center console lid at the Service Parts Identification Label. The options on your car will show on that list. If J55 is there, you have the larger front calipers option.

I believe the rears are the same on both base and J55, but I could be wrong there.

Best - AJ

Pretty sure the rears are all the same, just bigger in front if you have J55 which as ajp01 said, just look at the RPO sticker.
