2) My car had factory LCA sway bar brackets. I had to remove these for proper fit. Again, with going to the supplied 3/16" thick bracket (which is what I would have done anyway) it was no big deal since it'll be stronger than factory. It's just I wish I would have known this before I had everything installed. You may want to know this before you install on your car. It's alot easier to remove if your LCA is out of your car but it's not required. I removed mine with a pneumatic cut-off wheel and 2" sanding disk.
