The man wants MORE caster. How about this idea?

I like that. I always thought running loose wheel bearings and giving the rotors a shake at the the drag strip starting line might change times if you can stay out of the front brakes. Once again, splitting hairs. A good reason to run drum brakes if a drag racer. Okay, getting way off track.

Exactly!

To me it's the little stuff. Like knowing that the forces on the rotating tire are going to pull the slack out of your tie rod ends and steering components. So, that's why you set toe in, and for best results you want the toe on YOUR car to match the amount of slack getting pulled out of those components, to run close to 0 toe on the road. So if you've got brand new tight tie rod ends and steering arms you might want 1/16" toe in, but if you're stuff is a little looser you might want 1/8". And understanding that how the steering feels out on the road could tell you that you need more/less toe in.

Or you could just set it to the spec in the book and not worry about it, even if it's not perfect for your car it won't rip the tread off your tires. But some of those little adjustments can make a car feel a lot different.

Inherent from design bump steer geometry is not that big of deal with stock Mopar systems. Especially with street driving. Even spirited street driving.

Now if you have worn or incorrect parts that cause toe change and wondering then you have a problem. Most people call this bump steer. That’s not really bump steer geometry.

If you’re balancing your car in a 4 wheel drift all leaned over… bump steer is more of a factor.

100%, spot on. Lots of people confuse worn out parts and poor alignment settings for "bump steer". But really the time you're going to notice bump steer is hard into a corner with an uneven surface.

When I made the mistake of running 2" drop spindles on my Challenger that was when I actually noticed things weren't right. Doing some "spirited" driving/cornering on winding mountain roads. Under more standard street conditions it wasn't noticeable. When I was able to plug some geometry numbers into a program it was pretty clear that the 2" drop spindles increase bump steer noticeably compared to lowered the same with the stock spindles, and that was the unsettling feeling I was getting when I was pushing the car a bit harder into the corners.
