Default Jack placement

I wanted to take off my right front wheel on my 93 Coupe to check the brakes today. Got out the trusty floor jack and crawled under car where it said to put jack. All I could find to put jack under was the very edge of the frame were the body meets it any further in and I would have been on floor pan. Is that the place to put the jack on that thin ledge????

Take a look at that ledge- its solid and is part of the frame.
I don't jack it there, I go further into the frame.

I agree it's better to go to the frme if you can, I have also used a floor jack on the lip just catching the lip and not the floor board

When using either the floor jack or the stock jack I mostly just jack at the points indicated by the arrows under the rocker panels.

I recently did front & rear brakes and used those points for the floor jack when removing the wheels. Of course the puck on my floor jack has the cross slots so that it cannot slip in/out and risk taking out the floor boards or rocker panel.

if you're just lifting one corner, i lift where indicated by the arrows. but when i but the whole car up, i lift midway on the door, under the trailing edge of the mirror. with the z51 package, the car just comes right up. if you go under that lip you run the risk of hitting brake or fuel lines (depending on the side)

i can't jack it on that ledge without damaging the rocker panels. It dings em and pops the paint off. I dont even care anymore now.

Ha! Yeah, mine are like that, too. I had a couple of stress cracks in mine from where the car shifte slightly and the rocker panel lip dropped down into the cup of the jack. I don't car anymore, either. You'd have to get down on your stomach to see it anyway.

I put a hockey puck in the cup of the jack now and that seems to save the rocker panels. They still bend, though.
