Bump steer question

I bought a longacre gauge and tried it out today. I’m either doing something wrong or I have an issue. Here’s my findings. Seems pretty basic but maybe I’m buggered up.

- Passenger
- Compression.

.5” .055.
1”. .090.
1.5” .115.
2.0” .150

Drivers
- compression.

.5” .050.
1” .095.
1.5” .110.
2” .200

Pretty much everything. Stock k member, tubular uppers ( cap ), boxed lowers, firm feel box, 11/16 tie rods, hotchkiss strut rods. Stock spindles. I have a set of hotchkiss uppers I’m going to install eventually but I don’t think they will change bump steer without their bumpsteer kit.

For comparison, this is a car lowered 1" with stock spindles...

It's pretty hard to read, the original chart is listed here as well as a chart for the B or FMJ spindles https://www.hotrod.com/articles/mopp-0503-swapping-a-and-b-disc-brake-spindles/

With numbers like yours there's something pretty dramatic going on. You should be able to lower the car and change the caster and camber pretty significantly without inducing numbers like that. When you were installing those suspension parts did you also replace the lower control arm bushings? Check the K frame for cracks or damage, especially at the LCA pivot tubes? What procedure did you use to determine the length on the adjustable strut rods?

As for the CAP upper control arms, those things are garbage. If your plan is to run Hotchkis UCA's, install those before you put it back on the street. CAP UCA's have failed catastrophically due to poor welds.

Do you have your current alignment numbers?
