What does this stand for.... where do I find these specs?
"Pfadt street specs"
Thanks
We are a Corvette Performance Suspension design firm and have published a set of alignment specs for multiple different car setups. For street cars we suggest our Performance Street spec. It's within the range of GM tolerance, but the key is that the overall "green zone" of acceptable setting is smaller than the factory recommendation. By running a more precise alignment we find that the car reacts to driver input more effectively, while still giving good tire wear.
Keep in mind that your alignment is only as good as the tech performing the work. If you're taking your car to the dealer ask them before hand if they're comfortable setting up the car to these specs. There is plenty of adjustment within the factory hardware to easily achieve these numbers without any additional hardware or suspension changes.

Both my Firehawk and Vette have -1.0° camber and 0 toe...tires are wearing just fine. I don't like how the car drives with 0° and greater (+) camber, as it tends to promote understeer.
Thanks to all for the help on this, I am talking with the dealer now to see what they will do. So far seems like they don't speak English yet, told them when my lease is over I will not be back for the new C7.
They told me the other day at the dealer, its a performance car and tires don't last long. I would buy that if I spent everyday at the track running around at redline. Back and forth to work, 2 miles at a time is not high performance driving!

I just called my dealer (the local one the car was dropped shipped to) and the service manager said they do covette 4 wheel alignments all day long and that on a newer car they will only set it up per GM specs. "That way if you have issues down the road your covered"...
Maybe there is a better place in the valley of the sun to take my car to.
Our '10 GS wore the tires down to the belts in 5K miles. Dealer replaced them, but the OEM replacements didn't wear well either. I did get an alignment. GM will do one for you if you have between 1K and 7.5K miles on the car. Terrible set up for a car which most people drive on the road.

I was wondering about that... I can't vouch for all of them but if you have a Firestone dealer near you you might want to give them a try. They did my 2005 to the exact specs I asked for. They also have a lifetime alignment for $20-30 more so you'll never have to pay again.

I don't see any issues with that comment. The Pfadt specs are within the stock parameters. As long as they don't stray out of the stock parameters you are fine which would be hard since they are so wide you could drive a bus through the space. I don't have the GS settings but the 08 settings for the Z51 (FE3), Z06 (FE4) and ZR1 (FE5) should be close:
Pfadt Performance Street Settings are:
Front
Camber: -.7 to -.9
Caster: 7.5 to 8.5
Total Toe: .17 degrees to 0 GM lists Positive Toe is Toe In
Rear
Camber: -0.4 to -.6
Total Toe: .17 deg to 0
The front numbers easily fall within the stock specs for any version of the Vette while the rear lower settings don't have quite as much camber as the range allowed for the wide body stock settings. The higher number is right at the bottom or the range for the stock setting. A lot of alignment people just shoot to have the numbers within spec and you can see that can be all over the place. Just say you want the car aligned to certain numbers within the stock spec. That is what I do.
Salesman just called to tell me I bought the smart lease protect package and they cover tires. I guess will just keep having fun and see how generous they are when there bald! He did not say anything about the alignment issue, no surprise!
