diff. in housings?
 

okay i thought i saw this a little while ago but when i searched i could not find it. so are there any differences between front and rear rotor housings on a 3rd gen or can they be swapped? same for rotors? thanks for the help.

Doesn't only the rear housing have a bung in it for the knock sensor? Not sure if that would matter too much, I think I remember reading that at some point.

one has an 'F' and one has an 'R' or something like that to differentiate them. There weren't any obvious differences that I noted when I had mine apart.

thanks guys. does any one else know for sure? also does any one know about the rotors?

Rotors can be interchanged... also 20B rotors will work in the REW.
