From the tests I've seen a Brembo Car stops about 7-10ft shorter than the stock brakes from 60. They contribute 3-5ft of that to the upgraded tires though too. As stated above it allows for fast pad changes and from the tests the brake fade was the main difference on the track. For the brakes, rims, tires, springs I felt it was worth the 1675 or whatever it is.
