The rotards weights are WAY off. Just pull them from the rules if this is the best ya can do!

As has been pointed out, the car weighs a ton MORE in STL all while making no more power. When looking at the potential power to weights, it would make sense to allow the 13B WITH a street port - at 2600...and it still barely fits. Given the stock intake and AMD, around 190whp-200whp TOPS?

Probably a great place for ITS RX-7's but 250lbs of ballast in a Miata doesn't sound all that great for the trouble.

Suggestions:

12A - street port @ 2400
13B - street port @ 2600
