I like Brembo stuff - is there a bigger world wide company specialising in brakes out there?
The discs come with a good rust resistant finish that leaves the bell of the rear discs looking good + they also come with retaining screws...the only minor annoyance with those is its a cross head rather than torq, but better than nothing.
The standard pads stop well for normal road use -but if you are more a fast road driver you may want something with a more bite - and I can't say that I have noticed them producing much dust.
The Brembo catalogue is usually really detailed, down to car, that should confirm the pad size - but it doesn't seem to be working for me just now.
Front left is the only wheel with wear sensor - you may get the sensor with the new pads.
