Ride quality even worse than expected. Advice welcome.

Therein lies some of the problem. WHen you change a LOT of stuff, sometimes you run into things like this. It's sorta like a race car. All my life I've heard the old guys say "change one thing at a time" and it's true. If you shot gun it and the car slows down, what caused it? You won't know.

But sometimes with some of these kits, you don't have a choice. You have to change a lot of things at once and sometimes you're left with having to diagnose a new problem. I wish you were local, I'd come over and help you out. This is right up my alley. I did alignment and suspension work for years. I'm good at findin stuff. I know that's no help, but the sentiment is there. LOL I bet when you find it, you're gonna kick yourself.

That makes perfect sense...and while it's not a surprise, the suspension always seems like it should be simpler than it is. In reality, it's a system and each component contributes a new set of dynamic variables...messing with any one thing affects everything else and reminds us why it costs so damn much money to engineer a car from the ground up.
