If you're interested...
Looks like they sell motor mounts for the 5 as well. AWR makes a good product. Most people with my car get that for their rear mount and love it.
I was recommended that site from the forums that I'm a member of... mazdas247.com. I'm under the 6, MS6, and Atenza section but there's one for the 5 there as well. Anyways, they're quick, have good prices, and easy to deal with. Got a set of spark plugs from them and will probably be ordering a Turbo inlet and Short Ram intake from them as well in the near future.
