Brake caliper fitment / interchange

[cascade88]

I have a hawk wagon non turbo.

I can get a pair of front 4 pot calipers from a wrx, just wondering if the fitment is the same?

They are from a blob, non sti.

If they bolt right on, next question would be could I retain my original disk or have to use the wrx one?

Thanks in advance

I don't know 100% if the wrx calipers and discs will fit if the pcd is the same I would've thought so .

On the classics when you upgrade from front 2 pots to front 4 pots you have to use 4 pot discs (bigger dia) and pads(different shape)

If the pcd matches they will bolt on
