HDK Bump Steer 101

very nice......it seems now, you already know the answer to your question being very knowledgeable and certainly no rookie.

However....I used my antique / old measurin' tools to try to give you (and others) a fair answer to your question.

I measured 13", not 7.5", from the center of the spindle, so my numbers are a little strong. I figured that to be outer edge of a 26" tall tire. Honestly, most , certainly not all set-ups appear to be moving / bumpsteering so much , you can easily see the movement with you eye.

here are the results....

if it was off by
1* is .....3/16" or .1875 off center
2* is......13/32" or .40625 off center
3* is......5/8" or .625 off center

there ya go!....I think that is what you were after

Someday, I might get an bumpsteer guage that measure that precise, ....they look nice and do a hell of a job. I will have to put it on my wish list.

No question that is not a lot of bumpsteer in your HDK. Especially at 6" compression and 5"? extension. Really good at those high travels! Even though you didn't measure to the thousandth of an inch or the hundreth of a degree, it's still really good even factoring measurement +/- tolerances.

But I was just afraid someone reading this would assume you had .000" toe change or .00 degree toe change. Then see some other suspension with .040" toe or .05 degree change and think that was bad. That's not a fair comparison because one way records smaller measurements than another.

Now if something else was 1.82 degrees or .575" bumpsteer, well that is a 1/2"+ more than what Hemi Denny measured.

People in this thread are trying to draw comparisions to other K-members, kits, and suspensions. Nothing wrong with that. But please just compare apples to apples or put things in the same apple level.
