The problem with the Shelby drop was that the ball joints could bind and breal, that's why they have wedge spacers now, so you can lower the upper a-arm 1 3/4" and place the wedge spacer and have the balljoint sitting at the factory angle

Still need tech on "shelby stopped doing this drop becasue it cost more money for upgraded ball joints" but it seems a bit like a moot point anyway.

RE: Squealing Tires
I never heard he stopped doing it because of cost. The only problem I was aware of was that the drop with nothing else could cause the ball joints to bind, evenin a 1" drop if there was excessive enough suspension travel. I have heard Shelby originally did a 1.5" drop but breakage became an issue, so he went to a 1" drop instead.

I think Torsen only makes diffs for the 8.8, and the 9(and a few of the 4 bangers too). And yeah, theirs are all mechanical, but a LOT of mechanical, they have a crapload of parts in them. They use a complex set of worm gears and other gears to set a preload and tense wheel torque. They work, but they're heavy and complicated. Pretty trick setup though

I tried to buy one for a 9" a few years back and was told by Gleasman that Strange or Currie had bought ALL patent rights to the 9" version and the unit cost $1800.00. This was quite a shock as back in 1983 Ford was going to list them in the 1984 Hi-Po parts catolog for about $450.00.

Description of the T2-R, taken in part from here
Norm
The TORSEN T2-R takes the T-2's performance to the next level. By combining the patented Equvex gearing from the Torsen T-2 with a coil spring pre-load and/or friction enhancing plates, the Torsen T-2R can remain locked, providing torque to both wheels, under low torque inputs. The addition of the friction plates allows the Torque Bias Ratio(TBR) to be tailored to differential design needs. These features allow improved mobility and traction under extreme conditions. In addition, it is compatible with electronic traction control, providing the ultimate in traction management systems.

I remember reading about the T-2R before and being able to set the initial pre-load to have a different bias, but I think that's the only model they have like that. It's a trick setup, if not pricey

Ackerman on trucks/SUV's is more likely the cause for tire squeal than limited slip differentials. Unless you're running a locker, the diff will slip without a generous application of the throttle to lock it up.
