2017 318 RACE !! .... please join the fun

Are there a limited amount of actual ET submissions? Or just best of 2017?
Also, anyone can change the car as they go, just adjust according to the penalty box. Example, feel free to go from 2.94's to 3.91's, or from a stock converter to a street converter, just state the change and adjust the dial index accordingly.

We all can see what changes made what differences....
