Scion xd suspension on a yaris

[sasquatch]

Usually I would search more, but I'm feeling lazy today

I was wondering if xd suspension is the same as yaris. I have heard it is the same it looking for a definate answer. I ask because my girlfriend wants air ride on her yaris and I haven't found any yaris specific kits but have seen a few xd kits. It would just be nice to maybe save a little cash rather than hold a bag over coil setup. Then put the saved money toward a dope set of wheels :) thinking some classic Porsche wheels.

Thanks for any help!
