Talk to Jeff and see if K-Sport makes a kit for it. You could go with a set of springs and shocks, but then you're stuck with whatever ride height you end up with (most likely too low), and the shocks won't be matched to the springs. A low-end coilover kit like the K-Sport is a good value and gives you a lot of flexibility to set the car up at a ride height that works for you and adjust the damping for your personal preference between ride quality and handling.

The key to daily driving comfort is to retain some ride height and suspension travel to soak up the bumps.
