If the spindle is a 2" drop as stated it is surely the way to go. Lowering with the torsion bar screws the geometry up.
Career best 8.02 @ 169 at 3050# and 10" tires small block power.

There are drop spindles avaialable. IIRC Fatman fabrication makes them..

I'm dealing with this at the moment as well. Lower it down and camber goes to poop. Raise it up and the car wont transfer weight. Looking at everything from Tubular UCA's, Ajustable Heim Joint strut rods and everything else. Not sure which direction to go.

Adjust the camber again and re-align the car when you lower the car that much. Use offset Moog 7103 upper control arm bushing installed for more postive caster (don't follow instructions) to make the car easier to drive straighter (lower E.T.) down the strip.

How does it screw the geometry up?
It changes the alignment. So you re-align the car and move on.

The Bump steer goes to he!! when lowered.
Also, don't know about now, but when I sent my factory spindles out to lamb, there were no forged drop spindles. I think all the dropped spindles were two piece. This was about a year ago, so might've changed, but lamb wouldn't use anything but forged factory spindles.
The car sits low enough with the factory spindles and lowered torsion bars, but bump steer was addressed in the build...

Is that by yours/Lamb's bumpsteer measurements? How much worse did they get and where on the bumpsteer curve?
The bump steer curve doesn't alter when lowered. Just the zero start point changes so the end point jounce and rebound points all shift up. But things can get worse near the new endpoints.
There are forged dropped spindles on the market now. Came about a year or so ago.

As far as I know, forged Mopar drop-knuckles do not exist.
Magnum Force drop-kuckles are cast.
Looked back the ad for them you're right, cast. Isn't that pretty common with the aftermarket dropped spindles?

By your avatar I'm guessing you have an E-body (B-body same geometry). Hotchkis found that those front ends have a lot of bumpsteer. That's why they relocated the upper control arm pickup point. They said it was not nearly as bad on an A-bodies.

Yeah, E body and yes, gets pretty ugly at the ends. The starting point when lowered and at full extension.
The starting point in a drag car is minimal as the car should raise an inch from static on a pass, and you can limit the extension with limiters for launch, so manageable.
