Don't listen to that crap..
A motor mount should take any and all abuse you give it, period. It's a engineering defect on Mazda's part. They should stand up and fcuking admit it.
For 2007 we got 200-250 Red before Christmas
Now we are getting 200-250 mixed White, Cosmic Blue, or Black.
I don't remember if it was 200 or 250 each allocation, but the Number 500 total is accurate.
