The annual 24 Hours of Nurburgring race had a couple of S2000s participating.
Unfortunately, there is no other information is available on these cars at this time. There are obviously some things I'd like to know, such as what they are doing for rear brakes. You can see (barely) in some of the pictures that some of these cars have added much larger front brakes.
See the complete photo album of 311 images here: http://www.topspeed.com/blogs/nurburgring-stories/24h-nurburgring-2006-ar10878.html - Top Speed and Quentin Lhussier have done a fabulous job with the imagery. It's worth the time it will take to look thru them.
Unfortunately, I haven't yet found the race results online, much less all the team sites.
The event itself is for cars that are very close to stock - rules that are similar to SCCA T1. Bigger brakes, suspension tuning, roll cages and lots of safety gear - but not much else. In other words, something that we all can relate to. It's open to a wide variety of cars - you'll see an original Mini competing, an old Opel Monza GT, and a lot of newer cars including the latest European Civic (not to mention an Aston Martin and an orange Lambo). And the usual large number of M3s (mostly E36).
This is a great race that would be worth seeing - a hint to the Speed channel. I think that given limited time to travel in Europe on personal business, this would be more worthwhile than attending an F1 event because this is something that we can directly relate to, and learn from for our own race usage. We all love the sound of F1 engines, but this is something we can use ourselves.





One team site, in German, is here: http://www.honda-maeder.de/web/index2.htm I'm not clear on the translation, but it appears their car was destroyed in a crash...?
Seems that Maeder Motorsport GMBH has been busy with their S2000:
