Denny, I'm not "bitching". You made some comments about bump steer on these cars with factory suspension that are in fact not accurate. I know that for a fact because I've literally done the EXACT things you said would cause bump steer. And they don't. And frankly that shouldn't be that surprising because a well engineered suspension system should not be so susceptible to bump steer that changing the static alignment will result in a dramatic change.

Now, if you want to call that "bitching" and compare me to your wife, well, that says more about you than me.



I kinda don't think that was all he was doing. But maybe I'm wrong.

It's fine. I'll stop screwing up Tim's thread, I'm truly interested in his modifications and suspension geometry numbers because no one else that's done a coil over conversion has ever posted them.

According to the Mopar Performance chassis guide (there is a whole chapter on it) a well engineered system would include likely altering the steering arm / outer tie rod location.

And I am aware there are three arcs to contend with, LCA, UCA and tie rod, and when any one (or more) or those arcs are altered it affects bump steer....FACT. Some more...some less.
I don't know, maybe your suspension doesn't move enough to matter or your changes are in too small of increments to bother with checking, but if you don't think altering the steering curve by a 3 to 6 degree caster change happens, then you are not as informed as I thought you were.

...and OK, maybe that was a little low comparing your nagging with my wifes', If we would have been face to face, I would ask you what size skirt you wear. That's the way we handled it in my garage anyways and in extreme cases, followed by a bottle rocket (no tail) under the bathroom door. :) BTW....I have dodged my share of bottle rockets.
