Jack pad adapter question

I'm looking at photos of the pad adapters being used and I can't figure it out.

Which part of the adapter is supporting the car? The rectangular protrusion or the flat surface of the disk?

If it's just the rectangular part can't i just cut a small block of wood that would fit in that hole and use that?

The rectangular portion slides into the jack point on the car, the circular part meets the jack pad flush.



Small block of wood might work.

Depends on how much you jack the car I guess. The $20 for the adapter was worth it for me due to changing wheels @ track, etc.

Both. If you jack from some other part of the car, you do not need a jack pad adapter, but you will eventually crack the plastic jack pads if you do not have an adapter with the rectangular top that fills the recess in the pad adapter.

Don't most people use the front and rear jack points for swapping tires? Or is it better to get this adapter and use the four jack points on the sides?

Most jacks can't reach the front center jack point even on M3s running the stock ride height, so you either need a very expensive jack like an AC Hydraulics model, or you need to drive onto ramps before jacking, or you need to jack one side high enough to get a second jack under the front center (which is the same amount of work as doing one side at a time and also takes two jacks). The rear is reachable but I somehow don't like the idea of using the diff housing, so I just use each of the four side jack points one at a time. I bought two jack pad adapters in case I ever need to raise the car on two jacks simultaneously.

Do you have any idea how long and how low a floor jack needs to be to get under and reach the center jack points on the M3?

I always wanted to get the floor jack that griotsgarage sold. Alas, I waited too long and now it's gone. It looked like it was long and short enough to reach, but now I'll never know.


Cheers.

Sadly no, I've never measured it. Sorry!

The Harbor Freight one reaches, but the probably is that it's too tall. However, I don't mind driving up on a couple of 2x4's first, and then reaching the jack points. They can be had for $100 shipped and they are great quality IMO.

A block of wood will work, as these adapters' rectangular part are taller than the jack point depth anyway.

Full disclosure: I have and use the adapters.
