What are the advantages for a street only car?

Well, I am a big fan of the Elephant Racing Ploy-bronze solution, but the SPS does have some advantages. No maintenance, smoother action, (I was actually quite surprised by that, since the ER set-up was such an improvement over stock) and easier adjustability. It's also less work to install, since you don't have to remove any rubber bushings and clean and prep the old spring-plates.
The thing that really surprised me on the test drive, was that my 80% LSD with high pre-load, was no longer causing inconsistent handling.
The complete lack of friction really smothed out the small suspension movements, so much so, that the inside rear wheel was making better contact with the ground, which kept the cars attitude in a corner much more consistent. Before, any throttle input or pavement undulation would alter my car's trajectory, and I'd have to compensate.
It would likely be much less obvious on a standard diff. But I'm very happy with it. I did notice that afterwrds, it feels like I need to adjust the rear shocks a little firmer to re-balance the handling. I really wasn't expecting the difference to be much compared to the ER set-up.
For a street car, it is definitely a smoother ride, while still keeping the handling. It definitely gives you all the benefits of stiffer springs/shocks, but with less of the ill side-effects. I'd say it gives nearly as much improvement over the ER poly-bronze, that the ER poly-bronze gives over stock. And that's not taking anything away from Chuck's excellent product. I plan to use his poly-bronze bearings in the future anyime the customer choses them.
