The time had come for me to replace my front pads and discs as after 40k, they were pretty worn with only a couple of mm left on the pads. Also, after having the car remapped, I found the existing 312mm setup to be quite inadequate....I really started to lack confidence when de-accelerating from high speeds. I was told that by replacing the discs, pads and brake fluid I would see a significant improvement in braking performance....
