>>>I think what you're experiencing is not so much a reflection of how good
the Porterfield pads are (they are very good indeed), but rather how truly
awful the stock pads are.
The Porterfield pads will likely have a shorter lifespan, but that's
trivial on a car that is driven so rarely. The stock pads will look almost new
after 75K miles, because they don't work worth a damn. The Porterfield pads
are more sacrificial, but it's unlikely you will wear them out in your
lifetime.
I'm not aware of any adverse affects on brake rotors. While stock rotors
are plentiful, and should be cheap (it depends on where you get
them--sometimes they can be had for free if you're lucky), I wouldn't be in a hurry to
stampede towards the turning machine. If they are a little rough but have
no appreciable runout, I would just leave them alone....

Is there any downside to this R4S material, other than initial
cost? Short life? Eats rotors or drums? Otherwise seems too good
