First off ... note my changes below ... and then to "fill in the blanks" per Pontiac spec's and my dealer's alignment ...
Left Rear Toe ... Range = 0.03 0.37 ... Before 0.09 ...After 0.09
Left Front Camber ... Range = -0.7 0.3 ... Before -0.5 ...After -0.5
Right Front Camber ... Range = -0.7 0.3 ... Before -0.6 ...After -0.6
and Rob, you suggest replacing the springs ... WHY would this be ?
I mean if the alignment is within GM specifications ... what do you mean by ... "so negative" ... and then what is wrong with the OE springs?
Maybe you can educate me but from a layman like I am ... if it ain't broke why fix it? and if it's indeed "broken" then why is it still within GM spec's? I mean will I continue burning up tires even though the Dealer's shop said that I wouldn't?
So please ... "Larn me" ...
ok, your rear toe is not adjusted properly.Rob,
see my reply inserted below ...
ok, your rear toe is not adjusted properly.
while it is in 'spec' it's not what I'd consider close enough to consider it good.
The toe should be even on both sides, the more of a difference there is then the more the thrust angle is off.
As far as the rear camber, your at the limits of the rear camber, at rest with no load on the engine, is not a good thing.
When you accelerate, your camber will go more negative, and lean in on the top. This will increase your inner tire wear on the rear tires. The camber on my car is about -1.0 and i have stiffer springs so it doesn't squat anywhere near as much as with stock springs.
Just to give you an idea of what the 'tolerance' is. GM has a spec on how much a lower ball joint on a Blazer can be. I believe it's nearly 1/4". This is the spec they use to say a ball joint is not bad until it's more than 1/4" of play. Anyone that knows anything knows doing an alignment with ball joints that have 1/4" of play is useless, but GM says it's ok.
Your equivalent is your camber is at the tolerance due to the springs. With out replacing the springs it's not going to get better and you will still continue to wear your inner edges out.
just a thought from 10 feet away, but don't places around you offer a lifetime, or even just maybe a 5 year alignment for a few extra bucks? might be worth it for youAnd while I might be setting myself up for an "I told you so" down the road, I'm going to just stay with what I've got for now ... cuz by doing so, I will ...
1) save on the cost to buy new springs and get them installed.
2) avoid the cost of yet another alignment. ... which after two already done recently is really starting to add up!

but your rear toe/thrust angle is still out, and your camber is maxed
If my rear coil springs are indeed "shot", then why didn't the tire dealer try selling me on those replacements in addition to the tires?
on a more inquisitive note ... what is everybody else out there with '05 GTO's, manual shifts and 17" wheels running in the way of Toe, Camber and Thrust Angle settings on their last alignment? and are they working, i.e. do you have OE or after market parts?
Instead of trying to defend what you were told by the tire dealer OR the Pontiac Dealership- follow the directions given earlier and go measure the ride height YOURSELF, ask Rob or Frank to give you(if they haven't already) the proper ride height and you will SEE FOR YOURSELF that your rear springs are sagging and need to be replaced. It is common knowledge by almost all on this board that the sagging springs are partly caused by the long boat-ride from Australia and partly by the lack of tight enough quality control from GM on their tolerances for differences in spring height. Please just go out and measure them and report back here and if we are all wrong I will apoligize for every body. Not trying to be an ass, just trying to help you based on my own experience on spring heights with other GM vehicles.
