I've had the brakes for about 1000kms now so I can give some more rounded feedback.
Cold pedal (end of the driveway) is worse than stock. You have to push the pedal a touch harder to get the car to stop.
On the move and warmed up there is no difference to stock, but I did get some squeaking out of them on Sunday when it was hot (33c) and I was using the brakes a little. But that dissapeared once they cooled down.
I need to give the car a proper fang and test them when hot, but so far it's all good and the dust seems a little less.
