Are the rotors directional?
umm, there are only one way that the rotors can be installed. there is a stationaly gear on the outside. i'm not sure but i don't think it matters which one os which (front to back). just try to keep all you parts orginized and don't mix them up when rebuilding <-(safest thing)

beveled rotors, now that's something i've never seen before. nor has it ever crossed my mind to do that. cool idea. but just doing some thinking here.....it seems only the opening bevel would be necessary. why the bevel for the port closing when you can have the same effect by lengthening the port itself?

oohh good point.....but your hair covers it (j/k)
To the orginal poster. Unless you totally are rebuilding the Rotors I wouldn't swap them. In other words, there is a huge deal made out of Identifying and correctly replacing side seals etc when you are doing a rebuild. If you swap the rotors, then you are trying to get a seal to mate with a new surface and you are asking for trouble. In other words They wnat the side seal and corner seals to go back in the same slot the lived in for 100k miles. If you swap the Rotors the aren't rubbing agianst the surface that they were mated with for 100K miles. I'd go with the experts advice.
What happened.....did you forget to mark which was out of where?? You got a 50-50 chance of getting them back in there correctly.

You can do both: a streetport and beveling. This will push peak VE even further to the right (vs. RPM).
