Save yourself time and effort. you had the pre hung door measurements. make the framing fit with your 1/2" spare for shimming. 2) to shim a door quickly add a 1/8th or 3/16th shim in the door clearance (Between the door and door frame) This will preserve the clearance so you can shim the hinge side plumb (moves door and frame as one so it doesn't skew) tac shims with a brad to hold in place, place an extra set on both hinge and latch sides of the top plate of the frame to snug frame so it wont move when you open the door to install screws. recheck plumb as well as lateral so the door doesn't open or close itself. Something you did wrong was NOT installing the the backing plate above the door which is to support any finish going on the inside walls and allow for weather sealing. This is because you put a door with a 4" wide frame into a 6 or 8" transition (depends if you wanted casing or a set back) the reason 4" was wrong is the interior of the door should hang inside the frame by the thickness of the interior finish product. (Most common these days: Drywall) Garage drywall is fire guard 5/8" even 2 layers of. The issue is you've installed the door to overlap the brick pushing the frame towards to outside leaving no space for the finish inside you'll need to cut and add a lip on which any interior door casing can be applied. Which is why a 6" or 8" frame was needed. I've installed thousands of doors of all kinds. for this type since you did the framing as well you could save all the headaches by being straight square & plumb on a level surface.
