Which Pagid pad?
The braking program on the MDM should only activate if you are regularly achieving significant yaw in the turns, which isn't a very fast way around the circuit. That said, in my track experience, no way you can blow away a passenger-side pad set, in that short of a time, unless the caliper is hung or the pads are installed improperly. Possibly a set of stock pads at a racetrack that is hard on the brakes might disintegrate, but not racing pads.
Sounds very odd. I have gotten 8 full DE events (4 lapping sessions per event) out of my RS-19 front / RS-7 rears and they are at probably 30% remaining. My approach is typically slow-in/fast-out, so I'm very hard on the brakes. Rarely encounter fade on the two tracks I've run at (Mt. Tremblant and NHMS). I also usually run w/MDM on. Wear is very uniform all-around (four-corners).
Any more info you can provide? -Brian
