I have Goodridge stainless lines. They came from Rob at Needswings. I truthfully don't think you need them. They look nice and are harder to damage but other than that I didn't notice a difference. The story is they give a firmer pedal, less deflection. I now also have Porterfield RS4 pads and ATE Blue. When they are cold they take more pressure to stop. When they are hot they stop great. I feel like the pedal is not as firm as stock or stops on the street as easy. On the track they out perform the stock pads but it's not night and day. The real difference is they don't fade no matter how they are abused or how hot they get. (so far at least) The stock pads have enough grip to overpower the stock tires. So, in my assessment you don't want to change the stock pads unless your looking for less dust or you take the car to track day or autocross. Stock worked fine for me at the drag races. Now that my pads have a few track days on them they will squeal when cold. After a few stops the noise goes away. Just make a check list of how you realistically use the car to see if you need them or just want to change for looks or bragging. What works great at the track typically is not so good for everyday usage. Racing parts do look hot on any car. My opinion of course, from my experience.
