DOES THE HDK SUSPENSION K-MEMBER HANDLE BETTER THAN A T-BAR SUSPENSION?

Of course it is because there is no measurable value for human perception. However, as previously mentioned, my passenger who has been in the car for many miles commented that it "felt better". He was simply a passenger with only his *** being the connecting point to the car, no steering feedback in his hands. I wish I could explain it, but I can't. The only thing I can offer is a passenger seat for you to feel on your own.

I originally had springs of similar wheel rate to my 1.08 bars. Are the QA1 shocks better than the Fox Hotckis? Sure the double adjustable makes it more versitile, but is there damping actually better? Likely another subjective comment unless someone has compared the two on a shock dyno.

Likely my mistake. I've seen photos of fractured shock towers. Perhaps it was another brand.

I'll see what I can do about the toe change and camber change through suspension travel. That will take some time to measure. I also need to educate myself on the proper way to measure toe change with simple tools. I think the best way to see the roll center change would be to use the online tool.
Toe change is fairly simple. Remove the front springs. Put the wheels back on the front. Two pieces of plywood 2'×2' nailed to two pieces of 2×4 placed 1" from the tire with the LCA level to the floor. You can then raise and lower the wheel 1" at a time and plot the toe change. Check both sides to verify both are the same. You can then plot the height and toe on graph paper with left and right sides next to eachother but the + and - opposite. You get a good idea real quick of what is happening regarding toe change or as racers call "bump steer".
On a '48 Mercury truck I assisted on, the rack mounting was not done yet so we could C clamp the rack in a height we thought was appropriate. Then we tested the toe change. Then we moved the rack until we got the minimum toe change.
The inner rack tierod end pivot center should be along a line between the pivot center of the LCA and UCA. We found we needed a 1" spacer on each side, which was ordered. Once installed we retested toe change to verify. Once we were happy with that the rack mount could be welded to the cross member.
