I just took mine on a 1300 mile trip on the highway, with about 300 miles of mountain driving in the middle, coils on full firm, all the way down w/perches in and the fronts at the same level with plenty of thread to go, butter smooth the whole way. I absolutely love them. No body roll, no bounce, no slop, no harsh ride. The best way I can think of to decribe them is comfortable performance...they look pretty good too
Here's a pic they sent me right after install, before they settled. It's definitely lower now, and I'm about to drop the fronts a hair more too. Right now the top of my rear 225/40/18 tire sits just barely up inside the wheel well, and the perches are still in and there is plenty of thread left in the front so they go a lot lower.
