Disk brake parts swap
I see your retaliatory red X with no supporting evidence and raise you a "Red Brick", which has done 160 mph down the back straight at Willow Springs with FMJ spindles. mopar handling
Do FMJ spindles change the geometry? Yes, absolutely. Do they "screw up" the geometry? No, they do not. The numbers do not lie, you can see exactly what they do for/to the geometry in the article I posted. A small increase in bump steer for a better camber gain curve, the latter of which is more noticeable with wider, grippier front tires than the small change in bump steer (which can be corrected out if you like). Like I said, it's a trade off. Suspension geometry is ALWAYS a trade off. But I'm keeping the FMJ spindles on my Duster, and the "over-angling" of the ball joints is straight BS.
The "right" spindles are the ones that work best with your set up. If you're lowered and running wide, modern compound tires, the evidence shows the FMJ's are the right choice. If you're running at stock height with skinny little BFG's, it's not gonna matter at all either way.
