I apologize if you feel we didn't follow up properly. I agree it is our duty to provide the best possible customer service. 99% of the time we do an outstanding job (as told us by our customers, both happy and upset).
I understand the concept of following through with the customer. Beyond the automotive shows I attend I have very little contact with the "aftermarket" customer. My main responsibilities are development of electronic control systems and handling our more "OEM" type business; including but not limited to military and bus/van/recreational vehicle applications. When dealing with large corporations (and especially the military) constant flow of vital and correct information is detrimental to the progress of a project.
With that in mind I have spent the last hour pouring over previous posts to try to locate the cause of your problems. Here's what I found (I have included links to the threads so anyone who is interested can read them) (quoted posts were made by both you and your son):

After our initial conversation and subsequent solution you stated,
"These guys really work hard at customer service and the product is superior to anything out there.
Darren and Brit are the best !

"I am still have minor issues with the ride height. Before I had to ride in the 100's to get it not to bottom out and not grind when I take off. I was ok for awhile riding around the 70's and the ride was fantastic"
"The front works fine. The rear has the setting around 119 and the other side around 74."
We asked for you to check the height of the Shockwave at ride height, to which you replied,
"why is there a pressure gauge, if the pressure is not equal to make the car ride level?"

"I think you guys were really on it when you sent me the parts to repair my unit but I think you guys dropped the ball when Britt was in my area and would not give me the time a day to take a look at it"
"the ride height, it has to ride higher then I think it should and takes away the whole look of the car."
"The ride height or look, to stop the grinding noise in the rear end, is higher then I think it should be."
"I also noticed something about the tire clearance at this height. The drivers side clears by a mile, while the passenger side is too close for comfort going down the road. So either the rear isnt centered, or possibly the aftermarket 1/4s are not consistant, doubt the wheel backspacing isnt the same."
7/22/08 Darren asked: "Any signs of the u joints or shaft hitting the floor pan? Like Brit said, make sure that the drive shaft is not too long and bottoming out in the tranny.
Before welding on the upper links we made sure that the axle was centered perfectly between the quarters. Take a look at the upper bar bushings to make sure one of them is not damaged. Measure center to center on the upper bars as well to make sure they are the same length.
Try to get it on a drive on lift and take a closer look at things."

So based off previous conversations I can only ask that you put the vehicle on a lift and check EVERYTHING on the rear end. Why is the car leaning to one side? Why is the rear end out of whack? Are the bushings shot? Is the driveshaft rubbing? What is the pinion angle? After re-reading those posts I am now 100% confidant that there is no way to properly asses the situation without placing the car on a lift.
Once you have information for us I ask that you please post it on the forums, or better yet give us a call and discuss what you have found. Though I have failed in making sure your problem was solved, you have failed in providing any useful information that could help us diagnose this problem. I'm positive the issue can be located and resolved, but I'm going to need a little help from your end.
