Audi bolt pattern help please

Hi, Im trying to find an 18" space saver spare wheel to fit my Lexus. From my searching around ive concluded no one makes an 18" space saver in my bolt pattern 5 X 114.3 but ive come across a couple of 18" Audi wheels.

Audi S3 and Audi Q7

So my thoughts are my best bet would would be to use a hub adaptor although not ideal probs will be ok as hopefully I will never need to use it and if I do will strictly be a "get me home" use.

Does anyone know what the bolt pattern is on these two cars , Audi S3 and Audi Q7.

Thanks
Chris
