The first thing to remember is that any component that lowers the ride height of your vehicle will affect ride comfort (see a previous blog post titled "What Should I Expect from Lowering Springs?"). Even the most modest lowering spring (1.0" of drop or less) will affect ride comfort, but any coil-over setup will have a much more aggressive spring rate which translates to a firmer ride. In my mind, the coil-over suspension is intended for a driver that wants to maximize the handling of the vehicle in "track" conditions and also have the flexibility to adjust ride height (and damping rates) to suit track conditions. If local road conditions are poor, coil-overs will make a rough ride even rougher!
Eibach Multi-Pro Coil-Over R2
KW Variant 1 Coil-Over
The Eibach Multi-Pro Coil-Over R2 and the KW Variant 1 have the least "aggressive" spring rates, which will minimize the change to ride comfort but still improve handling and allow you to adjust your ride height for the perfect stance.

KW Variant 3 Coil-Over
The Bilstein PSS Coil-Over Kit and KW Variant 3 represent the elite in coil-over systems and provide the greatest range of adjustability for ride and ride height.
