Setup Questions from Readers

In response to a recent reader request, this post will kick off a more interactive way to blog.

The reader asked, "Would you mind answering some setup questions on the blog?"

You bet. Here we go. Send your questions in the comments to this post.

Let's do it this way:
1-Keep the questions short, punchy, and focused. It's difficult, if not impossible, to reply to something as broad as "How do I get rid of mid-corner understeer?" in a short answer.
2-If there are a lot of questions, I may have to pick and choose which ones to answer. If your question doesn't show up in the blog comments, it's either been delayed or set aside.
3-In this initial thread, why don't we limit questions to setup? Maybe we'll start another thread or two later for other topics, like "life as a race engineer", race strategy, organization and planning, etc. In other words, other topics in the scope of the blog.
4-I'm going to reserve the option to wrap up the thread, for later resurrection, if needed. My upcoming schedule is pretty busy and I'd rather avoid leaving a bunch of folks hanging.
