I'm looking at these upper control arms with locking/jam nuts on the inner mounts. How reliable are these? Looks to me that it could be very sketchy if one of those jam nuts were to back off. Do you really get a lot of use out of the adjustments in the real world? Is this something you would fool with after the car is dialled in? I would think the eccentrics would be enough .
As always , I stand to be corrected/properly informed!!
