YIKES!
Just to address- The wavetrak was chosen and installed because the #1 request was to remain streetable- or able to be driven to the track.
The helical style differential is an excellent option for and LSD in place of a clutch type as it has a basically unlimited service life, does not chatter, and offers seamless power transfer between the wheels.
We install them in many customers cars and have great feedback- dont knock it until you try it!
