IRS suspension alignment settings

[Jim Nilsen]

I keep going over the alignment specs from Vette Brakes website and still am not sure what settings to use. I am currently running at least -3 degrees in the rear and probably -1 to -2 in the front and am getting real good tire wear so far. The toe is feeling good but what it is exactly is still to be a mystery? I set it at just a tad in for starters. I did the best I could with a tape measure and it tracks real well on the street and over bumps. I can let go of the wheel and it goes straight, turn in is locked on like a cruise missle. When I want to turn it goes now with no delays and is right on to the corners.

I am looking for any input on what might be the best settings that others have experienced? I keep thinking I will go aggressive on the settings so I can get even tire wear with the hard cornering that is planned on. I keep telling myself that the same camber up front as in back would be good but normal specs usually have 1/2 as much in the rear.

So any of you who have or have had an IRS setup on a car, what was your favorite settings?

Thanks for any input.
