The infamous Miata Challenge (MC) auto-x/time attack double-header weekend is happening Nov. 21-22 at AAA Auto Club Speedway. Note, if you want to do both days (auto-x on Sat, Nov. 21st and time attack/open track on Sun, Nov. 22nd), you are eligible for a discount on Saturday's auto-x session for doing both days. Links/directions for that are at the bottom of this post.
This is also the second-to-last round of the MC 2009 series, and right now, Street Class is completely wide open for taking the 2009 season win. Mind you, it is rumored to be prizes for the season winners in each class, so if you are on the fence to sneak in late in the season to take the series win in Street Class, now's the time!
Also, in case you don't know, Speed Ventures has prizes for podium finishers (1st-3rd) for each class (street, modified, unlimited). The prizes are in the form of credits for future Speed Ventures events.
