Videos of Autobahn in Joliet

[sjs]

I'm looking for lap videos of the Autobahn circuits in Joliet Il. Specifically the North (1.4 mi) course but I'd like to get both. The ones on their site are very small and can't be saved for offline viewing.

Edit: I was able to pull their lap video from my cache so I have a local copy, but I'd still like something bigger/better.

Thanks!
