Alignment results

How do my alignment results look? Vehicle was darting back and forth (tramlining).

Before looked horrible... Camber out, and toe causing one axle to 'point' in a slightly different than the other (ie thrust angle). as you drive over undulations in the road the loading and unloading causes that weird darty-ness.

I guess they ignored/refused the request for 0.02 on toe?

You can see from the graphics why so many shops think that the very middle of the notch is best.... that extra 0.04 toe will cost you 5-8 or so in tire life.

Spot on alignment now, except for the toe....

I had requested 1 to 2 minutes of toe-in all the way around and actuals post adjustment were 0.05 to 0.06 inch or 0.05 to 0.06 degree. I didn't question it at the time as I needed to convert it to minutes. It was the end of the day and there were impatient customers behind me.

So converting my new toe values...
0.05 to 0.06 degree is 3 to 3.5 minutes which is a bit higher than I wanted.

How much will this impact things? Should I go back over and request a re-adjustment?

Are you sure your "in" are inches and not direction? To mix notation like that degrees and inches for similar measure meets is unconscionable.

There is no standard adjacent to the angle dimension when wheels are available in so many diameters.

Good point. Just sent email to alignment shop questioning the units and if they were in inches, why they didn't adjust as requested.

It says inches right on the alignment..."in"

Its confusing as they combine degrees and inches on the same page.



You are a tech type, so try this:

https://robrobinette.com/ConvertToeInchesToDegrees.htm

x5 tires are, approx 29.1" in diameter

so 0.06" is 0.0590677 degrees

or 3.54 minutes

Ive stated before: 0.02 in is just about 0.02 degrees...so almost doesnt matter. but DONT convert to minutes, IMO

On the calculator 0.02inch converts to 0.019689268210190625 degrees...damn close to 0.02 either way

That is a very balanced alignment, the ONLY thing you will notice is a bit less tire life. Thats all

Thanks ard...I had found the link that you suggested for conversion. I guess that I was getting messed up switching between minutes and decimal degrees and decimal inches.

Anyway, the vehicle drives much better now!

Now to tackle the jerky shifting.

Yes. You need to multiply the fractional degrees by 60 to get minutes.
