GC8 rear brakes :single pot to two pot - what needs to change?

[dubbedup]

Heya,

Have 2 cars, and i intend to swap the two pots off one and onto my single pot wrx, Is it just a bolt for bolt swap - basically swapping all the rear end, hub etc?

I have read a bit and understand the diff ratio is different, is there an easy way to rectify this? also have been told the rear axles are bigger is there a combo to allow me to keep my current diff in there?

TIA

All you should have to do is swap the caliper and rotors over.

EDIT: actually, would help if you told us what chassis and year the two cars are.

Both are GC8's (its in the title)

You can't for some reason - I have removed it for you

Cheers, Has anyone completed this without swapping in the diff and gearbox due to different axle and gear ratio?

One option is to replace the backplate and engineer up another, if the two pot doesn't just bolt up. I did this for a 4 pot upgrade over the two pot and a two pot reposition.
