Slight vibration '99 E55

I've noticed twice now my car seems to have a slight vibration under a acceleration with the A/C on and family in the car. Today my wife and 2 young daughters were driving back from the store with the air on. When giving the car gas to reach the speed limit. I noticed a slight vibration that seemed to be coming from the drive side. Within the last 10,000 miles I have replaced both motor mounts o2 sensors cats put NGK spark plugs and magnecore wires. I have not noticed the car doing ever with just me in the car. I did just lower using eibach pro kit and I reused the existing spring pads. I didn't replace the shocks. The car has 140,000 miles on it now. It has never seemed to do other than when there was someone else in the car with the ac on. No CEL so it leads me to believe that its not a misfire. Any suggestions to check would be great. Ohh and the problem was never there before I lowered the Car.

Thanks

Jonathan
