E-Series quiz!

[mcflux]

I've been lurking thru some other car forums and noticed that there's been a few quiz threads started up. I'm guessing it's OK to place here due to the content being on-topic.

So, here's how it works: I ask the first question (since I'm starting this thread :P). The first person to post the correct answer asks the next question. Limit of one answer per person per question (so no useless multiple posts, whores!). If you wish to change your answer, edit your post.

Questions can be short answer or multiple choice.

If question is incorrectly answered, the questioner or other posters can't say "wrong!" for 50x posts until the correct answer is given.

The person who answers correctly can then ask the next question, and the process continues Correct answer needs to be confirmed before a new question is posted up.

In a case where there is more than one correct answer, the poster who posted the first correct answer gets to ask the next question.

All questions must be E-Series related! Otherwise this thread is useless

The whole point to this thread is for a bit of trivial fun, and perhaps as a learning tool for those who read it.

So here goes:

What was the largest diameter wheel offered from the factory in the EB model range? Also, name the model(s) this size wheel was availble for.
