Got a Four Wheel Alignment Today - Toe Was Out of Spec On All 4 Wheels

As Zpirate said, the recommended spec range is so broad it borders on a joke. My interpretation of On Spec is the Spec number, not the allowable range of ERROR. Yes, you can scrub your tires off in no time and still have the numbers in range. Another reason NOT to go to your dealer for an alignment check, rather pay to have it done right to the correct number.

IMO, the factory spec is fine for aggressive street use.
Use the SPEC though and stay out of the "tolerance" range. A little wander to either side of center is OK, but for the most part it should be on the money. Insist on a before and after chart from your alignment guy and be very specific about your requirements. These numbers are already in his machine. The cruiser types here who most whine about tire wear, like to dial the camber closer to Zero. If you don't go around turns and don't play in the twisties that's OK I suppose. Many Corvettes are used like that.

If you are changing parts you are on your own for alignment specs, factory specs are for factory parts. Get a good local suspension/alignment shop and ask for for advice, tell him what you want. i.e.; Maximum tire life or Maximum handling, you won't get both with any alignment on factory or aftermarket suspension parts.

I just got back from getting mine done. I originally wanted -0.4 camber but he told me that I can go up to around -1.0 degree w/o having to worry too much about tire wear, as most tire wear is the result of incorrect toe. I know my Firehawk has -1.0 degree and has no issues with inside tire wear with my driving style, so I went with that.
I guess he aligned a guys track ZO6 with some pretty aggressive specs (-2.5 camber front and -2.0 camber rear) before the RA event. The had to remove some spacers in order to get that much negative camber The car owner was an instructor at the Corvette RA event a couple weeks ago.
Anyway, here's mine....how's this for a "spot-on" alignment! I was sitting right there with him while he was doing it too, no sitting in the waiting room wondering what's going on. This is my second time to this place, as I took my Firehawk to get it aligned 5 or 6 years ago and I was just as happy with how that turned out back then as well.
My factory alignment wasn't all that bad, but the changes were definitely noticeable!!
