Just picked up a set of SPF0877K Super Pro Eccentrics. The info here is somewhat limited(yes I did search). I'm hoping to compile all the info about then in this thread for future, easier use.
My car is an 04A4 with a Hinson 1piece driveshaft, lowered on Mavman coilovers and single adjustable springs. Every single bushing is Whiteline except these Super Pro eccentrics. I have a cradle alignment tool so my cradle came out for this process.
What quad eccentrics allow you to do is adjust toe and camber while losing the factory toerods. It is said the toerods will cause binding and could damage the diff if not removed. The inner bushings adjust toe while the outers camber. It's helpful to your tires to achieve 0° camber both for longevity and increasing your contact patch. Having a little negative camber helps in cornering, but I'm going for a drag/weekender setup.
So the rumor is the Whiteline single-bolt design is the best with the least chance of backing out, but they're discontinued. Apparently there was an issue with the Pedders eccentrics where the nut would back off and you could lose your bush and even the ear of the subframe that the control arm mounts to.
Duckman told me these Super Pros are the best on the market right now. Nordlock washers should be used instead of the split washers provided.
I saw another post Here that the Pedders bushings need to have the thicker inner lip of the bushing facing inwards. The Super Pros appear to be all the same thickness.
Here are the instructions that came with my set of Super Pro bushings:

Admittedly, I'm just a guy in his garage so I could be misinformed so feel free to chime in.
