So I was digging around for a toe calculator and came up with this one on the web.... seems kinda cool.... check my findings and let me know what ya think

Open the link then take a look below at my facts

http://aligned.hostcell.net/

A/B/C/D/E/F/G/H would be actually the difference you would like.. so 1/16th" difference in decimal format would be .0625 1/8th .125 1/32nd .03125

K would be Wheelbase which on a C5 is 104.5"

I and J would be inflated Tire Diameter which I used a NT05 295 35 18 of 26.18"

Calculate that and you come out with the degrees toe required based on your tire and wheelbase. :-)

From this calculator I need for 1/16 .14 degrees in on rear and .07 out on rear at 1/32

it's simple geometry, so I'm sure it is right. I measure at the rim though, not the tire edge, so it would be different than my measurements in that regard. Measuring at the rim, 1/32" is about 0.1deg. I can extrapolate/interpolate from there in my head.

RaleighSS

Thanks david..... so I can go forward and tell the alignment shop .07 and .14deg i guess.... maybe that will get me close enough to where I want to be right ?

You're saying 0.14 in at the front and 0.07 out at the rear?

The screen shot shows 0.14 in at the rear and 0.07 out at the front.

I think he wants 1/32 OUT in the front, and 1/16" IN in the rear.

Agreed

You can use this chart from Smart Racing Products:

Everone runs toe out in the front. Why? What does toe out do?

CorvetteZ51Racer

Improved turn in. Toe out makes that end of the car want to turn. So toe out in the front = good. Toe out in the rear = bad

RaleighSS

So all was trying to do here was obtain 1/32 OUT in the front, and 1/16" IN in the rear and get the numbers in deg for the alignment guy .... That is how the report comes out so figured I would just give it to them in deg....

Toe out helps turn in. OK
If both left and right tires have toe out and you turn left, the loaded right tire must first become straight and then turn to the left. This would seem to me to slow down the turn in on that tire. The unloaded left tire that is toed out should not be able to over come the right side loaded tire. What is there about toe out that causes better turn in? Just a question. Just discussing. Not arguing. Thanks.

Thats what I thought. The toe out is for Ackerman, not turn in. The setting of toe is for the proper Ackerman angle in the corner, including tire slip. Once you figure those angles out, that becomes the static toe.
You would not have static toe out, but toe in if you could have Ackerman too. This is done with steering arm angles. What do you think?
