I replaced my suspension with Redwood Motorsports coilovers (Grand Touring) on my 2022 Y LR with 19" factory wheels. I have a couple of specific suggestions:
1 - give the suspension time and miles to settle down before getting alignment. I am thinking 30+ days and 1000+ miles.
2 - It is important that you get the ride height to be square before doing the alignment. Think of the bottom plate of the car, if it is slightly twisted, then it will have "spring" in it... so get the ride height to be as close as possible, especially when comparing between left and right side (so the two fronts are the same and the two backs are the same). In my case, I wanted to keep the ride height the same as prior to suspension change. I measured it and recorded it at 179 mm, so I was trying to get as close to 179 mm on all 4 corners.
3 - Do the alignment with ballast, not without. This will help get your car ride as true as possible under driving conditions.
Attached are my alignment results - all measured and done about 3 months and 2000 miles after suspension replacement. Overall, I am pretty happy with the suspension upgrade (but it is not a perfect solution... as compared to a Model X...)
