I just installed Wavetrack few months ago and it is major improvement over my old worn out stock diff for one wheel spin around corners. In straight line, for street use, good sticky tires and stock diff is fine.Has anyone experienced the wavetrac launching on the street/strip? Was the car more balanced and predictable? Improved 60ft tomes? I'm thinking about going the harrop route to improve 60ft times. I already have 1000hp axles and stubs, dr's, and a 1pc ds.
