Just curious ... whats a TBD?

Torque biasing differential. Or limited slip differential.

Aaahhhaaa … LSD

Thanks

Torque biasing and LSD are slightly different but function very similarly on acceleration.

I had a sneaking suspicion that our pal euro911 would know a little something about LSD.....

His car back in the day...
