Eibach makes some high quality stuff, their race springs are world class, but they're not known for their dampers. It's honestly probably just a branding and marketing issue as for the money there's a lot of good stuff out there for whatever it is you want to do, spending a few thousand bucks is a risk and odds are selling them will be tough if you're not happy.
