So far I have been able to find http://www.renntechmercedes.com/
as a good place to get parts. Pretty soon I will be sending them my ECU to get it reprogramed and will let you all know how that goes. I have found a couple of other sites as well but I cant remember their names lol.
Woohoo I just remembered another one. http://www.ctd-germany.com/
They dont have alot of engine mods but their springs and breaks and rear diffusors are nice. If not a little pricey. Anyhow thats all I got lol.
