Hmmm, I'll have to look into some of those dates, for now I plan (if I can get in) to do 3 days at the Glen in July with the Delaware BMWCCA. In the meantime I have a busy AutoX schedule with SCCA, NASA and BMWCCA....
BTW your Watkins Glen video is great! Great editing (I have 10+years cutting experience myself...). I also use a D1 but I admmit that I was way too excited about the driving to taking good shots.
How did you like dealing with HMS? I'm considering making an appointment and driving up from NYC to get the harnessbar and belts installed. I would love to learn about the effects of the various suspension and chassis mods you did on your car.
