Air NEWB Geometry Question

[MONTEZ]

Being that I haven't been able to find exactly what I want for a rear suspension kit, I have been playing with the idea of building my own. I plan to use parallel bars on the sides with a bolt in hanger and weld on tabs/brackets on the axle. My concern is if I set it up for the lower bar to be parallel to the lower frame rail at ride height, where would I set my instant center to? I was thinking maybe at or slighty in front of the front bumper. Anyone have any advice on this?

You might want to look up robnolimit's thread "make it handle"

From what I have read in the past you would want to locate it around your front bumper.

"When any two bars are parallel to each other the instant center is considered "infinite." That means that the i.c. is states or even countries away and won't offer any dynamic energy transfer. The fact that the rearend is still following an arc set by two parallel bars it will still have anti-squat and roll-steer." Quote from Bio Max on SSM


And dv8 is right you want I.C to be at about the grille or front bumper...
