In the mail today comes a little brochure from
Reider Racing, that has (NEW!) an Auburn Gear
differential that looks pretty cool. It electrically
switches between a regular Auburn limited slip
and a pin-locked condition. Of course, Reider's web
site remains its usual unfriendly, no-prices-shown,
information-coming soon.

The brochure indicates retail "from" $595. This is
not so far off a T-2R price and depending on how
the un-pinned Auburn really behaves in the twisties
I could see this as an option. According to the
slick sheet, the Auburn biases torque to the wheel
with traction using some torque-driven clutch
compression (not just a static preload). My
question to the Auburn guys, here, is: do you power
through tight turns with one wheel spinning or none?

The exploded drawing shows plate clutches in a stack,
so I guess this unit is rebuildable unlike the cone types.

Pinning actuation is through a big-*** coil electromagnet
that (by the pictures) goes inside the case. Now I wonder
what effect this would have on those 3-channel ABS
rears where there's also the reluctor / ABS chopper
sitting kinda right there in the enhanced magnetic field.

They make no mention of what types of rear might be
supported with this chunk but I'd guess the S-10s /
baby Blazers (hence Camaros even if unintended) won't
be ignored.

From the limited material it sure looks like a good street/
strip differential. I'm mainly interested to know how an
Auburn (of this configuration, the plate-type) compares
against a T-2R in aggressive slalom (aka rush hour)
and hard turns (wet roads too) and take the lock option
as a twice-a-year track-day bonus.

Anyway, thought some of y'alls might find this an
interesting new development.
