Here's a shot of the passenger seat front bracket (closest to the door) before lowering:

Here's a shot after it's been cut and welded. Very straight forward. Just cut the part you want gone and drop it down. No fancy angles, Just cut.

Shots of the other brackets:
Inner front bracket (against the transmission tunnel).

Inner rear bracket (against the transmission tunnel). I cut off the section where the bolt hole connects on the WRX because it was hitting the floor. I elongated the hole to lower this bracket.

Rear outside bracket (towards the door).

That's it. If anyone wants any other shots, let me know and I can get them. Basic directions: Cut, Weld, Paint, Install.
