Slotted Rotors

[Greg Johnson]

OK, it's probably a silly question, but for those of us that are or have been
thinking about using slotted rotors on our Audis,  which way do the slots go?
Assume you are looking at the rotor face (front).  On one rotor the slots are "back
slash"  \ ;  On the other rotor, the slots are front slash /.   Which rotor goes on
the left side and which goes on the right?  Does it make any difference?  It would
seem that in one instance the squeezing brake pads will cause the gases and/or
moisture to flow towards the hub and in the other instance they would flow towards
the edge of the rotor.  Which is better and why?
