The factory rubber strut rod bushings are about a 1/2” thick. Under hard braking the LCA can almost completely collapse the rear strut rod bushing with its forward movement. So I’d say the LCA is capable of flexing forward a good 1/4”. That kind of forward movement isn’t possible with an adjustable strut rod, there’s nothing to compress to allow that kind of movement.
Here’s a clip of a video another member posted awhile back. Just watch the front of the strut rod when the wheel turns and the car comes to a stop. This is basic everyday driving, no hard stop, no hard corner.
