i've always heard these 2 ways... and i've never had many people debate about it.... my car works how it is so i may not change much... but i do know when the *** of my car was low it couldnt get any lift... now raised back up a little it's much better

IC ht. has nothing to do with the crank center line, I can set the engien on the roof...IC ht. has nothing to do with that, maybe your talking about center of gravity or something.... I dont know what you are talking about

You claim you know it all and have secrets you don't want to share, but your on here asking for help? You don't have the time to teach school but you have enough time to come on here and try and get some answers?
Whats the false information? What i said? If so your also disagreeing with jerry bickel and Don Ness. Don is the smartest guy out there when it comes to drag car suspension and for you to say hes wrong I cant help but laugh.
Show us exactly how you calculate IC.

your right it does not effect how the lines are drawn but it gives you a hint where the IC needs to be based on where the weight is in the car and how high and far back it is... geeeeez......

You can push up north, south, above, below or right at your center of gravity. shortening that torque arm makes it a lot easier to push to the south.

he's right. Motor height has nothing to do w/ instant center. but it does affect center of gravity, and hence where your ic needs to be located.
You can push up north, south, above, below or right at your center of gravity. shortening that torque arm makes it a lot easier to push to the south.

Mike, I believe that you are wrong about that one.
Relocation brackets are good for setting the lower control arm angle correctly. If they are pointing up it is very easy to put the IC so far back that it puts everything in a bind. Hence, so many broken torque arms on this site.
relo brackes make IC shorter

3rd link is only an upper link. IC can be moved up or down forward or back just like anything else.
I do realize one thing, Madman def has the best TA I have seen and I plan to get one this winter, he has all the adjustability built into it where it takes me several hours to make an adjustment and plot this out making brackets/links etc.

mdacton, the torque arm is not a third link. Think about a ladder bar. Its IC length is determined by the length of the ladder bar.
Think about this:
Put a rearend housing on jack stands and bolt on a set of ladder bars. Now stand behind the rear end and pull the top of the housing back towards you. What happens? The front of the ladder bar goes straight up and down. not backwards. the vertical motion shows the IC is the length of the ladder bar.
If you do the same for a 4link, the bottom link bars go forward, the top link bars go backwards.
If you do the same for a torque arm setup, the torque arm goes straight up and down just like the ladder bar. This is why its your IC length. The torque arm sees a vertical motion. not horizontal.
Gizmo is completely correct. Mdacton, again I would realy like to see your method on calculating a torque arm IC. Im VERY curious to see how you do it different then those that have proven the geometry in the picture i posted both on paper and in a pro stock car.

tq arm does not go straight up and down, thats why they have links on them or a sliding joint. Ride ht front or rear would also change IC
Why do you need my method? You say its flawed.... Good day sir

Be at richmond sat. Maybe I am wrong about all of it, feel free to come show me where I am wrong, If you teach me something I will gladly pay you if I go faster
