If it were necessary to lengthen the strut, but it’s not. Simply installing the adjustable strut rods that are commercially available would show you their range of motion is more than adequate to provide bind free motion through the whole range of suspension travel on these cars. The theory is sound, but it’s just not an issue in practice with the strut rods that are available.
My personal opinion is that for a street car, adjustable strut rods are a solution looking for a problem. It wasn't broke, but someone makes it for your car so you feel obligated to buy it.
You don’t have to build an engine with twice as much HP as the factory did either. Or run better tires or brakes either. But people do it don’t they?
The QA1 style strut rods on my Challenger had absolutely no issues in 70k miles, which is probably more miles than you’ll get out of any of the rubber replacement bushings currently available. And the adjustable struts absolutely help to improve handling. If all you do is putt around on sunny weekends and park on the grass at the local show, the rubber bushings will do just fine.
