Door installation questions.. please help

[98layinframe]

First off would like to say hi to everyone as I just signed up recently.

I have multiple questions for you guys since I'm currently building an addition onto my garage. Now that I have the garage framed in and closed up I'm starting to work on the door installation... and that's where my questions lay. First thing I noticed is the concrete guys poured the door step down a little uneven and the left side is about 3/8" lower then the right side. No big deal, but do I install the door with the lower panel sitting on the floor and then add the tracks in slightly parallelogram shaped? OR is the correct thing to just shim the low side of the door and space the track up so its level, then install everything perfectly level? (which is what Ive done so far.) The rubber seal is more then thick enough to close the gap to seal the opening on the low side, Im just worried about every time the door closes if its going to try and relax and shift itself in the opening.

The door is a 9'x9' with a 36" high overhead track and torsion style springs... So knowing the cables are tied together up top on the rod/drums will hold it level but its still something small that has me wondering.

I would install the door guides plumb and level. Let the rubber door threshold take care of the 3/8 difference. Do otherwise and you'll run into binding issues.

^^^ This... That's what the rubber threshold is for.

Level your bottom section in the opening. Whatever you shim the low side of the door, shim that track the same! This will insure equal tension on the cables when the door is open. Good Luck. :beer

3/8 isn't much.
Install the door square.
I have cut a wedge shaped shim to put across the bottom of a door.
But you should get by with a length of lath.

thanks for the responses guys, I did end up installing the door level and the lower rubber seal is more then thick enough to close the gap.

Now on to my next problem.. the springs. I'm using a used 9' x 11' high door my father gave me in my 9'x9' opening... so basically just removed one of the panels while leaving the tracks the stock height. I've purchased the high lift style drums, and have the new spec'd out springs and cables on back order. This has been quite a pain on the install... but atleast the $220 investment for a commercial size door is soothing things. haha

Why didn't you just use everything stock? The extra panel behind the header wouldn't hurt anything, and basically you could just rehang the door?
