3 and 4 link suspension help

[elmer91]

Anyone have experience setting up a 3 and 4 link? I downloaded the calculators from Pirate, but every thread asking for help was either "search" or a fighting match over what means what, this works better, etc. I gathered some advice from all of the threads, but the main problem i am finding is what i should shoot for as far as output numbers (Instant Center, Roll axis angle, Anti-squat percentage, etc).

If anyone has any advice, or has found a good thread about it, anything is appreciated.

The roll axis angle is important if you drive it on the street. You want that number close to zero. Too much anti squat you wil hop. Not enough anti squt it will squat and unload the front end. The problem with the calculators is all the numbers change when the instant center changes like going up a hill or down a hill. I read for days. Some say 100%AS some say more some say less. Makethe brackets where you have higher or lower holes to change the Anti squat

thanks! i have read to keep the anti squat between 65 and 135%, with a goal of 100%. have heard you want it at 0%, at 80%, and a bunch of other numbers. The roll axis angle wont matter much since this is offroad only. now time to get back reading and messing with the numbers.

I did a rear 4-link using the pirate calculator and have been very very happy with it.

There was a really good discusson on the board on optimum link separation, anti-squat etc. when I find it I will post up. I used the info in it for my build.
