Many thanks for your reaponses. If I interpret this correctly:
GT is the goto diff for track-oriented cars - better/newer tech than older factory LSD etc. And it's available with great customer service!
GT or Quaife (and others)
TBD operate much the same as each other? although from other threads it seems that Quaife is prone to self-destruction in high-power applications?
FWIW, I have a Quaife in my 914/6 GT rally car which works well for Autocross and rally with 200HP. For sure I've run into it's limitations on the track...
From Wavetrac's blurb - "During the transition from accel to decel, where you have near zero torque on the axle, even if the wheels are on the ground, the typical diff is unable to begin applying drive torque until AFTER the zero torque condition is over. While this condition is generally short-lived, the fact that most diffs can do nothing during that time means that there will be a delay once the zero torque condition stops - creating a reaction time in the driveline." - which is precisely what you experience with a
TBD or open diff and it's very noticeable.
Then Wavetrac goes on to explain how they are different. The question is how effective are these putative differences? Does anyone here have any real-world comparative experience re LSD vs
TBD vs Wavetrac? One oft-touted benefit of a
TBD is that it's more or less maintenance free. Could this be said of a Wavetrac and, if not, how would it's maintenance regime compare with that of (say) a GT LSD?
