What? Eibach springs are good. It would be excellent when paired with the koni yellows. However, they are not that low. Eibach sportlines would look a lot nicer and have about the same performance benefits.
For a little bit more you could indeed get the ground controls though, which again is more highly recommended, but it also uses eibach springs as well. It all depends how low you want to go and if you want adjustable. It would also be stiffer with the ground controls.
The top hats aren't needed. I don't even have them on my track car. In fact most people don't. It would be a waste of money for a street car for sure unless you are slammed.
