That link WAS to the Mazdamotorsports page.....in order to legally download that file you are required to be a member....AND to be a registered racer. by doing so without meeting those criteria...you are in fact illegally obtaining the material.
This has been discussed here a few times before...and on other boards as well.....
Mazdamotorsports has been contacted in the past to alert them to the illegal use of their site to obtain these manuals.
I highly recommend that you do not download the manual unless you are a registered RACING MEMBER of their site.
To ensure WE (the club) doesn't get into any trouble with mazdamotorsports...the link to the page was removed.
