Understanding Alignment Specs: help needed
I have a print out of alignment before measurements and need help understanding some things. Here's the specs:
Left Front
Chamber: -1.3
Caster: 1.5
Toe: .46
Right Front:
Chamber: -1.5
Caster: 1.9
Toe: .55
Total Toe: 1.01
On another website I found some manufacturer specs as follows:
Front Alignment Specs
The caster on the front end can range from +1.1 degrees to +2.1 degrees, but the ideal setting is +1.6 degrees. The camber can ranger from -0.34 degrees to -1.34 degrees, but the ideal setting is -0.84 degrees. The toe-in can range from zero degrees to +0.46 degrees, but the ideal setting is +0.23 degrees.
The questions is does the above specs mean the individual specs for each toe or the total toe?? It's very important for me to know asap. Thank you so much!!

I would always want some toe-in (positive toe) to reduce squirrelyness.
But too much toe-in will wear the tires on the outer side of the tread on both tires.
Wrong-Camber wear can sometimes be confused with toe in/out wear, however, I have seen toe in/out wear to have a feathered look to it. That is, looking at blocks of tread in the same line, the trailing edge of a tread block has a different wear depth than the leading edge of the same tread block. And this difference is repeated around the tire in that tread line.
Over the years, they have reduced the running toe-in in the design of cars to improve gas mileage. Once into the higher MPG ratings, every little bit helps. And running little to no toe-in doesn't cost them anything. We assume that they are using tighter-spec components to make this work, as overall manufacturing specs of mechanical components is a lot tighter than it was in say the 1970s.
