The trailing edge of your dash defines the edge of your dash. From that point back, your vehicle must pass the 30 inch rod test.

Ok well then if you build your dash 16" deep and completely flat from A-pillar to A-pillar you could make your dash 1/4" thick then correct?

About JL 13W7s, in another post I saw it brought up and I don't agree with the decision to disallow 13W7s in Street A.

The 13W7 is 107 square inches of cone verses 2 Kicker L7 10" which are about 130 square inches per pair,

OR

13W7 frame area of 14" = 154 square inches verses a single L7 12" (12.5"^2) = 156.25, or even two ROUND 10" at 108 cone/157 frame square inches, I see the 13W7 as a perfectly fair option verses of a pair of 10", and a single round 12" to actually be a handicap in the Street A class.

The simple fact is, the 13W7 is advertised just as that, a 13" woofer. Last I checked, 13" was bigger than 12". In fact, JL literature claims something to the effect of "having more displacement than a 15" woofer".

JL makes a 12W7 and a 10W7, both perfect candidates for Street A. 13W7's belong in Street B.

Can't get any clearer then that.

In answer to your question "...Who cares", I imagine JL Audio and those who would have one 13W7 and might wish to compete in DB Drag.
I would expect that to be obvious, and as far as displacement, that isn't all that important in well-tuned ported enclosures, plus there are several pairs of 10" which have as much displacement as a single 13W7.
..and No, I do not plan to use one, - not thinking of me, rather the fairness of the class to as large a percentage of equipment owners and competitors as possible, rather than having an attitude of, "Who cares?".

I would consider that ok for any 12inch class but too big for any 10inch class. I dunno.
