Don't think the fastboyswest-website will be of big help here! There are 3 good tracks within like an hour from Ramstein, best one is Ettlingen, followed by Saarbrucken and Wiesbaden. Here are the links to the 3 tracks websites (sorry, all in German...):
Very nice facility, 1/5-Worlds took place there 2 years ago and also nice with Sedan's.
Saarbrucken/Niederwurzbach: unfortunately didn't find a website...
Rather boring layout. Pretty rough surface, so make sure you bring enough tyres...
