Disk brake parts swap
Yes, the FMJ spindles are slightly taller. You can see that in the pictures from the article I linked
The article, which was written by Bill Reilly, does a great job at looking at the differences in geometry and breaking down the changes that occur because of that. Ultimately, the changes are VERY minor. Like the vast majority of people will never be able to tell the difference the way these cars are usually driven.
For most builds there is no reason to seek out, or avoid, FMJ spindles. At this point even the FMJ cars are not that easy to find in junk yards anymore, so a big part of the utility is gone. But I’m sure a lot of people missed out on a cheap disk brake upgrade because they bought into Ehrenberger’s BS.
I have the FMJ spindles on both my Challenger and my Duster, but part of that was that I was able to pull them from the local yard for cheap. I do run the wide, sticky tires that make their improvement in camber gain more relevant, so I will absolutely be keeping them for that reason. But if I had 73+ A/E spindles I wouldn’t go out of my way to convert to FMJ’s either.
