Do these cars have any adjustment for rear camber?

Yes.

Thanks Ray!

I'd like to see a bit of negative camber on the rear as well as the front.:)

Yes, all 4 wheels are camber adjustable.

So that means you can install the aftermarket spring kit and that wheels can be aligned correctly?

yup

with the extreme kit from pedders i am running on the following negative camber:

lf: -0.32
rf: -0.35
lr: -1.29
rr: -1.19

Do you know what it's set at stock? BTW, thanks for the info.!

With an Extreme Pedders kit, you will be able to get -1.0 to -1.2 negatrive fornt cambers and -1.5 rear cambers with no tire wear concerns, unless you drag race, which -1.5 negative camber is not appropirate for drags

How can you run negative camber without causing uneven tire wear?

Also, what's with the rear toe-in? Seems odd on a rear wheel drive car, as under acceleration the wheels will be pulled forward, creating more toe in, increasing understeer tendencies. Or am I missing something?

Right facts, but wrong conclusion. Rear toe-in will indeed help the rear of the car go straight (understeer). That means, as you turn, the rear of the car tries to go straight. But, because we're at the back of the car, this creates OVERsteer up front.

For autox (where you are constantly turning), most guys run a few 32nds toe OUT up front and a few 32nds toe IN at the rear.

Control allow increased camber without excessive tire wear. The OE suspension is soft and tall. There is an enormous range of travel when you drive down an ordinary road. With each bump, there is a corresponding change in functional alignment or dynamic alignment angles. If you pull a bone stock G8 onto an alignment rack and put in five people and luggage the camber will increase almost 2 full degrees. Do the same is a fully Pedderised G8 and the camber will change less than half a degree. The answer is control.

In this first example it is all about spring rate. In this section it is about damping and bushes. The OE radius rod bush is a hydraulically damped bush. It works very well for ordinary driving. It is marginal for an aggressive driver and worthless on the track. There isn't a race track knowledgeable person that willingly runs a hydraulically damped bush on the track. They are too compliant. Movement in the radius rod arm from excessive bush movement changes castor. The same would be true of a control arm, the sub-frame, differential and so on. All thus bush mush, this bush squirm allows the angles in the alignment to change in a large range. Pedderised those changes are under control.

Finally when the suspension is dialed in and well balanced we add in our blade adjustable sway bars, bushes and endlinks. These are the final tuning step in your suspension. By further limiting body lean and roll we again limit the range of alignment angle changes that occur under driving loads.

Because the suspension has been upgraded to function at a higher level we can run a more aggressive alignment and still get excellent tire life. It isn't black magic. It is Pedders RED Magic. We designed a complete system for the G8. The Alignment specs on mu G8 are -1.3 Front and -1.7 rear, We use minimal toe at .02/3. The castor increase is +1.5. The tires are wearing evenly, They have been rotated twice. I have 8K on them. There is a bit of center wear on the tires, but I suspect I know the source of that.

Pete, you have coil-overs, right?
What would be a set of alignment specs for a GT with the full track II used as a daily driver but with a small bias toward improved handling?

As long as you do at least a TracvkII system, where all the bushes are replaced, springs and shocks upgraded you can run Petes specs for aggressive street play. Not real good, however, for drag racing.

For the record, I have the only other set of chrome polished Pedders Extreme coil overs like Petes in th world and they are available

You guys have it all covered. I am not needed :whine::cry::cursin:
