I beg to differ talonx, I agree with DJlantis on this and can say from experience. You are correct in THEORY, but where the rubber hits the road ther are REAL differences in effective, actual camber with different wheel offsets due to exactly what dj said: leverage at the fulcrum point.
This probably only applies to the Trackick front ends as it relies on the strut and coil length as well as weight to set camber. Most other IFS type suspensions have upper AND lower control arms and camber is not nearly as affected by coil, leverage and wheel issues, if at all.
You can set up your Trackick to have 0 camber (ideal) with one set of rims and tires, say 32" on 8" rim with 3.5" backspace and swap for a different offset wheel/tire combination and you will get a different camber setting because of the increased/decreased leverage caused by the offset changing the leverage point. I've swapped wheels and tire combinations, from a 8" with 32's and 3.5 backspacing to 5.5" stock rims with 31 swampers and almost no backspacing and indeed there is a noticeable difference in camber.
This is exactly why Calmini reccomends a specific rim backspacing for their lift, 3.5" I believe, to provide the correct leverage, ride height, and camber adjustability. Once your lift is all finished and you have the tires and rims your going to run installed, get a proper alignment and camber adjustment so it's set to factory spec, 0 degrees camber 0 degrees toe, and if you get a chance, just for ha ha's, swap to a stock set of rims and tires if you got them. You'll see the diff.
