I have run the both ferodo formula and ds2500 pads. Both on track days at collie, i actully felt that the formula had a far better pedal feel.

both were worn after a day of laps, but the 2500's had slightly more left. Neither had enough for another day of the same amount of driving. I would say you could get about 150km of track driving on the formula and 200km on the 2500's. On the street significantly more.

The 1170's are the pads for the subaru 4 piston calipers. so i would say the others would fit the brembo's.
