I agree with everything you've said, Quantra. Everyone does it a certain way, the only thing that matters in the end is lap times
Just to clarify, when I pick the front of the car up by the chassis (in the middle), I look for the front wheels to lift up at the same time, but I'm adjusting the rear springs to ensure they do. So I do one end of the car at a given time. When I lift the rear, I look for the rear wheels to lift up at the same time and adjust the front springs accordingly. But you're right, this assumes you've gotten the droop screws exactly even. It's pretty close with droop blocks and a droop gauge, but in the end we're talking about plastic toy cars
