I get the idea of trading off comfort for performance - thats just not whats happening here.
Agreed.

There is no reason to believe that the OP's stated issue/concern is a function of all high performance braking systems; there are many other cars with high performance brakes that don't seem to have a problem trapping rocks between the rotor and dust shield. My Jaguar has their "superperformance brakes" and there haven't been any reported issues with stone trapment in the past 4 years that I've been a member of that forum...
