    So according to this document the min/max toe is -0.01 and 0.29, so I'm assuming the target I should aim for is the average right between them at 0.14 degrees. That means I need to add -0.31 to the left and 0.21 to the right. Should I get one half-degree shim plus one quarter-degree shim, or two half-degree shims? And the shims will have the documentation for how to adjust them to get this number of degrees for this particular vehicle? I'm looking at the MOOG K66601 and K66602, but another thread on here said that it had conflicting information for gen 3 prius. Hope to do this right so the car doesn't :)

    I really couldn't tell you usually my alignment person tells me what shims he or she wants to get to fix the red if it shims in fact that I need. And I usually just let them order them and then install them and go from there That's something that I don't really try to fool with I guess I could but then I have to drive the car back over there so they can put it on the machine to make sure it's in the green now so since they're already doing that well there you go That's one of those things that I just take the hit on and I have a guy that's very reasonable so it's not too bad I'm also in the country where a lot of y'all are is very expensive I do get that. But in a bad alignment and bad suspension components equal tire wear out much quicker and cost rise quickly so best to have the alignment correct so I can get max mileage from the tires thereby saving something.

    This is an excerpt from the Repair Manual, the rear toe spec:

    (full repair manual wheel alignment section attached).

    Without coffee I'm not quite sure if you're within spec's or not.

    Are you having any problems, say uneven tire wear? Has the car been hit in the rear? If no to both, I'd be inclined to leave it be.

    yes it pulls to the right even after tie rod alignment, yes the tires always wear out prematurely at the edges and yes it has
