Are you all rod ends then? I have stock exhaust, so noise is a bit of a concern. I know I'll have to put up with some, but if there's chunking and clunking and rattles, I just can't deal with that, LOL.

The factory rubber allows enough off-axis movement to avoid this, and spherical ends of course allow movement in all directions up to their limits of travel.

I think a lot of people have a mistaken belief that the factory links are somehow not good. All those links react tension and compression forces only, so their resistance to bending and torsion is irrelevant. Moving to spherical bearings will eliminate the squish of factory rubber bushings, but they will be noisier and they will tend to wear out with street use, so you'll be replacing the bearings from time to time. I don't know enough about drag racing these cars to say if you would benefit from them, but otherwise stick with the stock links and put your money into others. The toe links are very worthwhile for those who want to get more rear negative camber than the stock links allow. But you're not tracking or autocrossing your car, so you don't need them either.
I get what you're saying. That all makes sense. Where I'm concerned is I'm on DRs and with a 2650. No - a 2650 will not hit as hard from a dig as a 1740, but, let's just say there's going to be more torque available than what the stock 1750 calibration allows. So - because the stock parts are all designed around a power limit (that's already limiting), I'm wondering if when those limits are reduced, if those stock parts will put up with what I want to dish out.

I'm still trying to figure out the benefit proposition. I'm not trying to make this a weekend warrior. I don't street race - I'll mess around, but I don't race in Mexico. I'll go to the strip (eventually) but I'm not sure I'm willing to put up with too much in the face of all of that. I feel like the ZLE bushings will do a lot in keeping the cradle from dancing too much, and that seems right up my alley. Is that grand going to hurt or help me?... That's what I'm hoping to glean from you guys.

Thanks for the comments. I am reading them.
