Needed to do some work underneath the Spyder and was very nervous about using a high lift as I don't really know where the jacking points are! Managed to use the pit instead.

I presume the front and rear jacking points are where the metalwork bolts through the monocoque as I assume lots of strength there as the bolts must go somewhere. Am I right in my assumption or is there going to be a large cracking sound if I jack at that point?

Jack behind the front wheel,in line, and in front of the rear wheel on the four corners of the monocoque.

You can jack anywhere along the sill in the 'wheel tracks' and on the front and rear edges of the main body. Avoid the beam end covers in front of the rear wheels though!

Thank you, I was basically right, now to go and fit the new rear tyres.
