Next, ride around in the car for a while (at least a week or so) to let the suspension settle. If the car does move you can go back in and adjust the ride height.
Next, get the car aligned. Depending on how old your car is you may want to consider changing out various bushings in the suspension system. In my case, the new suspension (which is also made by Ground Control) pretty much used up whatever life was left in my stock lower control arm bushings and rear trailing arm bushings (as a result the car "wiggles" under hard load).
Once the car is aligned, get it corner weighted, preferably with you in the car. Keep in mind however that you may end up with a car that doesn't look even (i.e. the right side may look higher than the left, etc.). You want to make sure you take variable weight items out of your car that you don't intend to race with like spare tires, jacks, subwoofers, etc. as they apply to your car.
One thing you need to keep in mind is that the new suspension system on your car is totaly different than the stock one. And as such it will ride differently. When I say differently, that doesn't necessarily mean more harsh (since that is very subjective anyway). I don't know how much your car weighs, but the stiffer the spring rate on a light car will increase ride harshness. That is why, for example, if you take the spring rates on my car (450f/550r) and put them on Trip's car, Trip's car will ride harsher than mine because his car is lighter. I know this since I am more familiar with BMWs but this fact still applies to all cars.
Good luck.
I think you will want to get the cornerweighting done and then the alignment. Even the small adjustments on the corners will move the camber or toe. Go to Eurosport this doesn't seem like a do-it-yourself job
