I'm impressed with the talent, skill and brain power that it takes to build a custom chassis with independent suspension. So one of you enlightened builders may be able to help my situation. I have a Butler Racing Cobra that I'm building. I have a Jag IRS and a IFS by Fast Cars. I've done the installation of both IFS & IRS units and I'm trying to figure out how to correctly measure everything for proper alignment.

But before I loose anymore sleep I may be trying too hard to get the measurements perfect. Perfect matters with suspension and that can only be good, but how much deviation should one accept.

Here is my situation. I've adjusted and measure my wheel base and the measurement is perfect between left & right. But when I measure diagonally to check for squareness, one diagonal measurement is 1/4" longer. Will this amount of misalignment seriously effect the performance.

I would have to setup a number of reference lines, etc. to try to locate where the alignment is off. But before I do this is is worth it to correct 1/4"

Thanks for any assistance,

Arthur
