SA/U

- Any ECU mods allowed (standalones allowed)
- Tire Restrictions
- AWD/RWD -- DOT approved drag radials

I was placed in SA/U due to my EWG. Honestly I would have much preferred to be in straight up SA as that's where all my friends (as well as closer competition) was.
That being said, if GT-R's show up again, it's basically an auto win in SA for them. I can't think of any other import that can trap 135+ with bolt-ons and still look completely stock. It will be interesting to see how MAP writes the rules this year.
