Tire Q - 21x8x13 on 8in wheel?

[TeamFRD]

Has anyone tried the Pro Mazda tire for the rears on a FC or air cooled FSV?
I'm think it will lower my CG and change the gearing just enough in a autocross application.

I wa planning to try them but found that they were hard to get, almost like you have to have a pro-mazda before they would sell them to you. But they would fit fine on an 8" wheel, I would expect, but I believe that they are intended as a front application.
