For a good street alignment that corners and luanches well without unusual tire wear here is what I suggest.

Front
Camber -1.2 per side
Toe bring it to ZERO. It will help with turn in, but will not eat your tires

Rear
Camber bring it done to as close to -5 degrees as you can get. This will help with tire bite at luanch and dial out a bit of understeer.
Your 5th Gen had toe eccentrics when it left the factory. Have the tech set you rear thrust angle to ZERO at something like.12 as showing on you sheet. When the sides are matched the thrust angle will be ZERO

Ok Pete.. give me your alignment setup for a person who is looking for street use only and the best tire wear. And will I be able to get this alignment without buying extra parts. Should be receiving your coils soon.

Camber -.75 per side
Toe .17

Rear

I dont understand the statement in red. Are you saying set the thrust at zero or .12 I didnt know if that was a typo or over my head talk lol

Well....got my car re-aligned yesterday. Had him tune the bushings. The guy spent a good 2hrs doing everything and I watched as he loosened up everything.

My dad rode along with me because he didn't have anything going on. Funny thing was that he was commenting how springy it felt on the way to the shop.

Afterwards we both agreed that some to the springy feeling was gone. You still feel dips in the road but you are going to get that even from the factory with these cars.

All in All I'm very glad I had it done. What was even better is that he only charged me $100. I think that's because we started doing some bench racing while he was working. He has a C5 Z06 that he had just put a supercharger on. So, over the course of those 2 hrs or so we had some good talks about our cars and racing them at the track.

Very cool in several ways.

poor wording on my part. Set the toe to something moderate like .12. With both sides matched, both sides with the same tow reading, the thrusta angle will be zero.

There is no factory castor adjustment so it is a fixed measurement, unless you have installed Pedders castor eccentric bolts

OK here it goes, When my car had the stock Rims and tires and springs I could run it up to 125+mph or so and the car felt tight to the road, I changed the wheels/tires lowered 1in with springs, Now at 125 it feels loose in the front like it's walking side to side. Kind of scary. I took the settings pdfat gave for Performance street and the guy told me it would eat my tires off. Instead of arguing with him I just had set it to stock. Still feels lose at high speeds.

MY question is if I have them set to pdfats setting will it fix the high speed problem? and will it make it eat the inside of the tires off faster?

A Camaro set to OE specs should not wander. Can you post your actual alignment numbers?

I have no idea, he gave me nothing. I changed to Toyo Proxes 4's All season would that matter?

Everything matters, but we are really shooting in the dark without actual alignment specs. Castor can cause a wander. Toe out can cause a high speed wander. The main issue we would have with an OE alignment is the 'green' range. The tolerance covers a wide range in an OE alignment. Tires can too. You can use Pedders, Hotchkis, Pfadt or even OE and they will all work IF the alignment is tight to the specifications. i.e. -.75 degrees negative front camber would mean exactly -.75 on both wheels and not -.25 on one and -1.1 on the other.

What I suggest you do is print off your alignment spec of choice for your 5th Gen and take it with you to the alignment shop. Tell them you want a Pedders spec alignment, a tight tolerance alignment, and want a before and after print out. Make it clear that you'll settle for nothing less and ask them what they will charge to do it this way. Getting a green range alignment takes the tech half or a third of the time. Doing it spot on dead nuts accurate will take longer. If it doesn't solve your problem then that would lead us to your tires. Sorting the too out starts with a really good alignment.
