Mazda 3 Suspension Systems Reviews Check out this recent Mazda 3 Eibach Sportline Springs customer review: Kenneth L from Boise, ID says "I am so happy that I went with the sportline springs. I am more of a looks over performance person but these springs give you the best of both worlds. The drop that these springs give you is amazing. The ride is a little bummpy but I left stock struts in. I would def recommend these springs to anybody that has a MAZDA 3. If you are going for the most drop possible these are def the spring. Nothing comes close to these."
