Back in the Feb issue there was a neat LSD comparison of 3 LSD units in an S2000. I have a question about the Red Line oil you used. My KAAZ unit clearly stated that I must use their product for best results. I have had a few clutch type diffs in my Z cars over the years, and all have "chattered" badly when driven gently. Is their an oil that will make this go away that will not affect the diffs performance? Did your KAAZ unit chatter when driven around the paddock?
