I've only installed them on the back of my Ford Fusion. Significantly better braking performance. I've been using EBC Greenstuff brake pads for 12 years and they stop the car better than any other pad. I had a car service that transported people to airports and I've tried almost every brand. There is no special break-in process required, just install and go. However, you must be careful not to over-pedal as these pads grip faster than other brands. The only drawback is the high price.
