I've been running these rotors on my Evo 9 MR for 8 years and only on my second set. They are great rotors for street and track use. With the Raybestos ST43 pads I can pound on them all day at the track and not have any hot spots, cracking, or warping. The only disadvantage to these rear rotors is that the center hat is larger than stock and any pads you buy will have to be cut to fit around the hat. If you have an angle grinder it's not too much of a problem.
