What do I need to do... What do I need to do to keep my car from scraping? I have the Prokit with stock shocks. Running 18" Z06's wrapped by 275/40's. The tires will rub under heavy acceleration (ie pedal to the metal) or when I turn sharp. I've been able to keep the tires from rubbing by not punchin the gas 
and not takin my baby through the twisties. Will new shocks fix this? Adjustable Panhard bar? Or is there something I can do that is free that will fix it? Any help is appreciated.

Better shocks in the rear will help control the suspension better. The stock ones are pretty sloppy and allow the rear to compress more than it needs to.
Are they tire rubbing on the inside or outside?
If the tires are rubbing on only one side, then an adjustable PHR will let you center the rear axle to prevent this. The harder the bushings the less the car will move to the side, so a rod-end bar would help the most.
If that doesn't fix it, a little more ride height or spring rate in the rear will help. You can add spacers like this for little money.
Finally, if the tire is catching the fender lips, they can be turned upward at a 45* angle to prevent cutting the tires.

The Eibach rear springs have a bad reputation for being too low and soft in the back. By far the easiest thing to do is add some simple spacers.

They run about $5 for a set of 4, can be found at your local auto parts store and are very easy to install or remove. Just lift the rear of the car to unload the spring and put one in the middle area of each spring making sure it isn't going to touch the body. Then lower the car. The weight will keep it in place. One metal spacer will lift it about 1/4" and increase the spring rate just a little. Both are good things. If you need to go higher, install another spacer on the same coil but 180* apart from one another.
If you ever decide you don't like it, just take them out and you will be 5 bucks poorer, so no big deal.
I've been using them for over a year with no problems at all.
