I believe that should be in the service manual, but maybe they only have it for the front. What generation are you looking for?

Gen 3. I looked in the manual and I can’t find where it specifically states the change in degrees per turn.

I guess in theory there is no need to know since you would measure it as you adjust to get where you want.

I’m just having a rough run with getting any sort of work done for the Viper, either bad quality work, really far away shops or unresponsiveness which is starting to force me down the route of doing everything myself.

Oh, you mean how much the toe changes with one rotation of the link? Sorry, I was thinking of the toe change as the wheel cycled up and down. That wouldn't be in the manual.

You can kind of calculate it, but I'm trying to recall what it was when I did my last alignment. I think the threading is ~16 threads per inch, so each turn should be 1/16" in link length, which at the wheel would probably be closer to 1/8-1/12" due to the wheel be further away from the pivot than the link. I'm not sure what that translates to in degrees off the top of my head, but should be easy enough to calculate. I've typically always worked in distances for toe though, though a lot of the data out there is in degrees.

Thanks! That actually helps alot. I think the last shop gave me toe out instead of in which made the car super unstable in tight turns. I know what the specs they aligned it to so with some math can figure out about how much to bring it in.

I should have 1/10th of an in Toe Out so 1 turn would bring it to neutral and then another turn should give me a bit of toe in.

Looks like two full turns should do it.
