Zero slop on the link ends of these 3D printed plastic links, using PTEG plastic. These links snap fit over the balls and hold with spring force tight against the ball.
I get the same kind of lack of height precision with the stock links too.
I do notice that the brackets holding the ride height sensors are pretty flimsy aluminum bent form shapes that can easily be moved with an index finger poking them. Let me tell you a story...
After I had my rear motor changed and I was riding around with a rear corner that was almost 2" different in ride height that the rest of the corners, at all settings. And I didn't notice this for more than a year. I installed an adjustable link to dial that corner back into equivalence. Eventually I brought the car in to have the height recalibrated on stock links, thinking they missed a software calibrate step on one corner after doing the motor work. When I picked up the car, it was riding perfectly even again. I asked about the resolution and the tech said "bent the bracket back to it's proper position", he said sometimes when they're doing motor / axle work we bump the sensor mounts, usually remember to check height but this one escaped. I asked, "so no software recalibration required to level the car?" .. "Nope, just moved the bracket."
