Sometimes it is good to stir the proverbial pot to see what rises to the surface. It is indeed interesting for me when comments are made to analyze why the person making each comment says what they do.
I personally do not use them on customer's vehicles unless I am instructed to, however we have run them on our own personal vehicles, --most notably on a Model A that was in the GreatRace a couple of times where we needed to have the utmost control over the vehicle during mandated speeds. I am however of the opinion that just like modern shock absorbers, when something is installed with little or no regard for match-engineering, then it can be a deterent instead of an advantage. Therefore my position is that Model A's driven as they were designed & engineered to be driven probably will not see a huge improvement however since most Model A owners choose to modify because it seems to be the right thing to do on their Model A (which is generally not properly maintained), then they are probably a slight improvement, -or up to a huge improvement. The one thing that can be argued is what does it hurt having one installed? If someone complains about it becoming difficult to steer with, I refer back to the vehicle being properly maintained.
