No, that only pertains to the old Legacy Turbo LSDs. The RS/WRX LSDs use the male axle ends just like the open diffs. The difference, as far as I can tell, is length. The length is subtle enough that the open diff axles will appear to fit with the LSD. I didn't want to take that chance so I bought axles for a 2001 2.5RS.
