I finally mounted my new RE01-Rs the other day. Well, my mechanic did. I told him to save the fronts just in case anyone here wanted them. The manufacture date is 4 years ago. I've had them for 3 years and have put about 17K miles on them (the same as the worn rears that were also replaced). He claims that there is 80-90% left on them (I guess I am not the racer I think I am!). I find that hard to believe, but I haven't looked at them lately and he is the professional. I don't really want to deal with shipping them, so If anyone wants them and can pick them up in Torrance, CA, lemme know by PM!
