1/4 mile car front end alignment

The best thing to do is get video of the car about 1/3 track right after the front end has settled to where it will carry. Note the space between the front fender and tire and duplicate that height on the alignment machine. That way, the alignment will be correct with the car at speed instead of static, which is what you want. As for specs, I would start with the stock specs, but with the front end raised as described and work from there.
