I'm aware of the 100 posts on this in the past. I have no question on how to change it, rather where to purchase one. About 8 months ago I bought the competition mount from mazdamotorsports. Last night I snapped the mount. My rear shocks are completely blown, and with the aftermarket clutch I would just get insane wheelhop. I was late to work and downshifted into first, and slammed it into second. SNAP. I knew instantly what it was. Well I just checked mazdamotorsports for the 62 dollar mount and apparently they only sell to 'racers' now. Great. I attend a few solo II events a year, and drag every couple of months, however I'm not a member of scca or any other organization so I can't join the site. Is there any other place that offers that same 62 dollar mount, or is it unique to mazdamotorsports?

 

I am pretty sure that Mazdatrix.com sells competition differential mounts. They might even be the Mazda Motorsports ones, just a little more expensive.

 

I believe Jason at the RX-7 Store (see the add at the top of the page) can get any Mazdasport item, as well as Mazdaformace.com

 

mazdatrix sells the exact same mount but it's $90...

if you have papers / pics etc proving of your solo events you should be able to get a membership. you don't need Scca stuff.
