I've got the Steeda Sport Springs w/Tokico D-Specs on my 06. I also went with their heavy duty upper strut mounts, adjustable panhard bar and brace, rear sway bar, G-trac and strut tower braces. Everyone that has ridden in the car has complimented the comfort level.

 

I bought Eibach Pros for my daily driver and I honestly don't notice much decrease in ride quality at all.
