   It doesn't matter; it still involves too high of an RPM, which can cause   
   engine damage.   
      
   I try not to habitually downshift for engine braking, but that depends   
   on the car.  If a car has a weak or failing braking system, I'm more   
   likely to downshift, but not anywhere near where the red line would be.   
     Weak clutch, and you'd better be more generous with the brakes.
