ok - been fitted for a week and a bit, 300 miles done
here are my INITIAL thoughts over the standard setup.
the brakes have instant bite over OEM audi ones and there seems to be little fade in heavy breaking
the pedal feels firmer and you dont need as much preassure to stop the car
the disks are slightly and i mean slightly more noisy than OEM, but you only hear when the window is down
my diveway is more like the side of a mountain - i kid you not, the oem could not hold the car, the new ones could, so much so that on saturday it was 33 down my way - chatham, kent , that the car stayed still and my drive gave way !! the tarmac was ripped up a bit - will post pic later tonight !!!
all in all - not properly run in yet but i would say 20% better than oem and mine were 1/2 the price
