Actually, the website claims that it is progressive and ultimately locks
the diff because the friction plates tilt. I don't see how, but that's
just me. And the installation site shows gears being modified to provide
more friction. I don't thing rubbing a steel block against the gears is
going to be a very controllable LSD.
I'm still not getting it.

Jack,
I don't think anyone is claiming that it Locks or makes the Diff stronger.
It's pretty obvious for that happen you must change the the diff all
together or have the weak links in the original made from stronger
materials and adding locking unit, which you know means much more than
$270.00. But if you're looking for a better setup than a open Diff, than
this would be a option for you. As Jerry Alford has stated it is new for
us in VARA and testing and results are on the way. Steve's GT6 will
definitely be putting some torque to that unit and I can hardly wait to
race against him in Buttonwillow and get some insight. I personally love
my Det. Locker, but I setup for that "PUSH". I also race with welded
Diffs, "the cheapest of the solutions" big Push! I have checked into a
clutch type unit and it's going to be $600.00 a diff and it will be custom
for each Diff. WOW 3 x $600.00!!! Custom parts and clutches, HMMM!, not
winning any money for this hobby makes it tough to justify! I think I'm
going to wait for some results and hope they are good. I have all kinds of
questions since it is metal to metal essentially. What type of gear oil
you they use? Will it make a difference to use synthetic? Do they
recommend additives? Inquiring minds want to know and I'm sure Jerry A.
and Steve S. will post results as they gather more track time on these
units! Good Luck Guys!
