So how much movement in inches is that? The graph is only showing like .4? And is that first spike in the upward direction showing the rear end going away from the body, ie, extension on the shock?

Ken, I set in on an inch scale so it's just above the .4 line so it's about a 1/2 inch
of extension......Yes the zero line is at rest above the line is extension and below the zero is compression as is the minuses sign... =;

I don't have a shock travel sensor but video of my car leaving shows much more than a half inch of travel extension at the hit?

Where is your IC and anti-squat?

Mine extends and compresses a little more than that but it doesn't extend the 2nd time like Barry's does. Mine stays slightly compressed for most of the run.

IC is about 55" and it's 4" off the ground.....As Scott would say "don't care where
the squat is =; =; =; "

beretta when you posted your fourlink geometry for me to run in my prog you posted that the lower bar mounts were 7.75" off the ground both ends of the bar. If thats true then your IC cant be 4" it has to be 7.75" So what gives?? Did i run the wrong numbers???

That # was before I changed the lower front of the bar....I can give you a new measurement for that if you want..

Yeah I think he's running a Scott Smith suspension setup now. ;-)

Ok, now we are getting somewhere. in fact, you have raised the IC closer to the neutral line and it works better. This is a point I was trying to make that no matter what the thought process behind a change that works, or improves things, it still agrees with the physics controlling it. Now how far out is this 7.75? What is the relationship between the IC and the neutral line as compared to the lower setting? Are percentages closer or farther apart.

I think that any setting change that shows any real improvement, will agree with standard physics. There are cases that shock/spring resistance can alter IC effects for a short time. This was one of the points that Shrinker was trying to get across when he said higher IC are more stable down track. I think. Maybe we can make sense out of this thread yet.

Ah Dennis, I think he moved that lower front bar location down not up? Scott likes that bar to be down bubble in the front about 2 or 3 *. That would put it farther away from that "neutral" line you speak of, yes/no? Is the "neutral" line also known as the anti/squat line that runs from the rear tire patch to the front axle CL at CG?

That confuses me. How can you move bottom bar down and get higher IC?

Yes neutral line is 100% anti squat line.

Dennis I moved the front of the bottom bar down and right now im at 4" above the ground........And yes I can get a higher IC by moving the back of the bottom bar by just moving it down a hole......... =;

OK my bad. Thought you went from 4 to the 7.75.
