I have a Brembo '14 and when it comes to it, I will definitely reuse stock springs and just shock it up. Good tires and shocks will make a world of difference, especially on a non-Brembo car. The road here aren't awesome and lowering is a lot more about looks than performance. Lowering a Macstrut equipped car can actually make it handle worse, particularly in the rain, even if done correctly, as you take away some range of suspension action when you do this and requires high spring rates to compensate. Race cars deal with this by changing the suspension geometry but, that's not feasible on the road and the road is no racetrack.
