Who is FSD? If you mean Koni, where are you getting your information?

What to do? Start by giving Koni more credit than what you read on an open forum:
Look at the screen capture from http://www.koni-na.com/fsd.cfm below.
Notice how the third point from the top marked with ">" describes lowering with Eibach springs?
If you lower your car by more than 1.5" you will tend to bottom the suspension on larger bumps due to a lack of travel - this will be harsh unless you use springs and shocks that are stiff enough to prevent bottoming: these will be harsh even on small bumps. Then there is scraping the nose and floor of your lowered car – why lower a car below one of the standard OEM heights? There are several height set for different models and markets.
