[s-cars] Slotted Rotors

[Jimmy Pribble, Managing Editor, UrS4.com]

Greg,

My Zimmerman rotors slotted by Weston Motorsports (Hi Paul!) are both
slotted "back."  That is, facing the rotor, the slot curves clockwise from
inside to the outside.  I think this is the correct configuration, but I'm
not exactly sure why.  I'm guessing it has something to do with the angle
that the slot cuts across the pad.

Anybody have the Reynold's number on that?
