Do you have an account on the main site? It's easier to submit vehicles there directly. I could add them for you, but then you will not be able to change info, like episode numbers, ratings, class, etc.

You can create an account here for the main site:

I set up the title here:
http://www.imcdb.org/movie.php?id=13684264

We would also need the episode number and star-ratings for these cars.

Like I said, I can add them for you if you'd rather. Let us know, thanks!
