From experience I can say that they make a difference on many cars. But, at a previous discussion here it was well decided that on the S2000 they don't make much of a difference if any. Possibly our cars have better rubber lines than what your average car does. I put SS lines on my S but also went to 6 piston brakes at the same time. It made a difference but I can't say it was the lines.

he means master cyclinder. A bigger one might apply more force requiring less pedal effort. I would start with changing pads before touching the brakelines.
