dont have the time to teach school, no offense dude....... but you guys are talking and im not hearing what I want to
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 ass of my car was low it couldnt get any lift... now raised back up a little it's much better
the higher you set a motor in a car the easier it is to tip the car up... and so on for a motor thats lower....
ic height will depend on motor height....
no it will not sir, as I previously stated you are wrong and I do not have time to teach school to you. Go do some home work.....
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
relo brackes make IC shorter, basic stuff...... I know all that
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.
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......

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.

Darren..... think about the 3rd link in these cars.....IC is not fixed.
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.

your wrong, it is not like a ladder bar you have 2 independeny mounting point on the housing it can pivit from each one, hat means somewhere along the line they have an intersecting point.
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
You say I'm wrong but you don't even know how to explain your method? I see your in VA. Where do you race at? I'de love to see how your car works at the track.

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
