Finally got tired of cleaning wheels 4 times a week so hoping to get the TRW ceramics on this weekend. When I did the 13 XF I couldn't find what looked to be a suitable floor jack and jack stand point under there so I used the factory jack but would prefer of course to use something a bit more stable. Anybody have a diagram or a good description on where I want to jack it up at? So much plastic under there.

 

The jacking points and the axle stand points are different and I usually use both when doing something under either the rear or the front, eg two trolley jacks and two axle stands for added security and safety.
The jacking points are designed to be used with the OEM scissor jack but you should only ever use that jack for a roadside emergency, otherwise use a trolley jack or similar.
The jacking points are about 3 cm inside the bottom edges of the sills, on/around fairly substantial pinch welds, where the idea is that the slot in the head of the scissor jack fits around the metal "tongue" of the pinch weld. If instead you are using a trolley jack then it helps to use a slotted "puck" or similar to go around the tongue otherwise after a few times that tongue will bend (don't ask me how I know this!)
On XFs that don't have the "aero" sills there are small triangle shaped markings on the bottom of the sills which point to the jacking points, but there are no such markings on the "aero" sills (such as those on the XFR), so on those models you really have no choice but to eyeball the jacking points first.
The axle stand points are further inboard, on solid metal chassis parts, but the front ones are well inboard and not easy to get to and the rear ones are very close to the jacking points which makes it a little difficult to get axle stands under them with a trolley jack already in place. With some perseverance and wiggling they will juuust fit!
Here's a diagram of the axle stand points:

 

I always use a hockey puck between jack pad and the jacking point; works great and inexpensive too.
