Rear pads on MINI R55/56's wear fast.
I've also always had significantly more brake dust on front than rear wheels. Extra things at play if you're getting more dust from the rears - different compound or issues with the brakes.

"Another factor that has accelerated brake wear (especially rear brake wear) in certain late model vehicles is the change to electronic brake proportioning. The proportioning valve that normally reduces hydraulic pressure to the rear brakes has been eliminated so the rear brakes will handle a higher percentage of the brake load and be more aggressive. The antilock brake system performs the job of brake proportioning by keeping an eye on how the rear brakes are behaving. If the rear brakes start to lock up when braking hard, the ABS system kicks in and cycles pressure to the rear wheels to prevent them from skidding.
This approach helps the vehicle stop in a shorter distance, but also increases rear brake wear dramatically. This means the rear brakes will often wear out before the front brakes."

Going from 20% of the braking to 30% of the braking would mean that are handling a higher percentage of the braking."Another factor that has accelerated brake wear (especially rear brake wear) in certain late model vehicles is the change to electronic brake proportioning.

....and we know the rear brake pads will wear out quicker, but if you've ever seen rear brake pads, most cars have thinner and smaller pads on the rear.
