hey guys. I got UK 4 pots in the front and DBA slotted rotors for the fronts also. But now I am trying to figgure ouw what kinda upgrade I should do for the back.
I don't think 2 pots are nessary so I am thinking of just going with upgrading the rotors to a larger size. What do you guys think? What size?

You can do what a lot of others do and that is put on the Legacy rear rotor. I believe that you will need the brackets as well. I know that there is something that you will need to get. But in all honesty, the fronts are more important that the rears since most of your braking power is in the front.
