so I 5 lug swapped my fc and I got new rotors and pads so the new rotors are slotted in the rear so my caliper doesn’t fit them so I need a new caliper or bracket for it?

 

5 lug rears are vented (at least usually, I seem to recall some models with solid 5 lug rears). 4 lug rears are solid.

Anyways, if you are using the vented rear rotors then you need the wider caliper that came on GXL and Turbo models.

 

I believe the caliper casting that you are looking for is 1313. Most parts stores have them listed under "hard" suspension.

 

plan B is to use the rear rotor from a 89-91 Base model/soft suspension, its 5 lug but not vented so you can keep your existing calipers. the Mazda part number is G0YD-26-251A

 

I think it’s worthwhile to make sure you upgrade to 4 pot fronts and vented rears if it’s in your budget.

 

after looking at it a bit more the rotors are bigger too is that normal for the vented one. I got my parts on discount on rock auto so idk what they are.
but the 5 lug swap came with the car when I bought it just no rotors or wheels.
