I ask because when I do my alignments I have to create the "level plane" for the scales since my garage is not level. After dropping the car and driving it around, the measurement will be off since the ground is not level. Its only after getting it back up on the level plane will I have the same, relative measurements. I have learned this is also the case when a car comes from an alignment shop and someone else's garage. The measurement is always slightly different based on calibration and levelness of the plane. Hopefully that makes sense.

 

Yeah, I calculated the result in degrees and forgot to multiply by 60 to convert to minutes. I edited it shortly thereafter, but apparently not before you quoted it. But you really want to use tire diameter, not just wheel diameter, unless you actually measured toe without any tires mounted on the wheels. That's how I got my (edited) +5 min.

 

I don't see any reason to run any toe up front. At 0 the car doesn't wander too much or anything like that and 0 is better for turn in. If you cared more about track alignment, I might even recommend slight toe out.

 

Save your self the math exercise .

Again, that only looks at wheel diameter, not tire diameter, which isn't appropriate if you measured toe while tires were mounted to the wheels. But here's a more accurate way to save yourself the math as long as you're willing to look up tire diameter somewhere like Tire Rack (and possibly do basic conversions like inches to mm and degrees to minutes): https://robrobinette.com/ConvertToeInchesToDegrees.htm
