John L., I think that they would be great for the track, but I think that anyone with old rubber bushings or hard plastic bushings would want to switch to these because of the limitations of the original design. I don't understand why it is thought that these may transfer more noise into the cabin when they are really just a pivot point, and the shock and torsion bar really take care of the aforementioned vibration (that's their job - not the bushings).

Most suppliers no longer carry the stock replacement rubber bushings, and the only way that I have heard that you can get them is to purchase them integrated into a new or refurbished A-Arm. And if you are able to source the originals, then you "may" eventually run into the issue of the bushings "flowing" or changing shape which could alter expensive alignment work.
