Default Attention! Superdown owners!

anyone with superdowns experience any vibration after lowering? I lowered my car Sunday and since then I get a vibration from the rear. (Seat vibrates a little)

i cant take this anymore, I made a previous thread about it but I'll list what I did. I already got an alignment, I'm getting my tires balanced Saturday.

So it only happens at highway speeds. 70+ if I'm cruising off the gas, it won't vibrate. Once I'm on the throttle LIGHTLY to gain speed, it'll cause vibration in the seat. ONLY upon throttle tho.

My right rear wheel has no weights, but before it was lowered it drove like a cloud. Now it's ****ing annoying and I'm about to take off the springs if the balance doesn't solve anything. I'm so frustrated

anyone else have issues ???

2014 AWD F sport

Don't have superdowns, but it could be the drive shaft from the transmission to the differential, or the shafts from the differential to the rear wheels(not sure of the name). When you lower/lift your car/truck you can only go so low/high before the ujoints in the drive shafts starts to bind.

I've lowered every car/truck i have owned to include a lowrider with hydraulics. Binding ujoints would be my first guess since it only vibrates at certain speeds when you give it gas.
