Cup-car info

[juse]

To Oliver and other german enthusiasts;
I`ve been searching trough net for technical information of serious beetle-racers like Dr.Gerold, Klaus Rashig and other käfer-cup-like stuff...and the result is next to nothing.
There is this one site that looked interesting
http://home.t-online.de/home/UweH.Reuter/homepage.htm
but it`s mostly in german of course. Think I`ll have to get a german dictionary from library..
So are there any sites, literature or other information sources you can recommend to me?
I`m building my slowly progressing project for autoslalom or similar class for streetlegal viechiles.
