I have run a lot of spericals on track over the years, but if you're going to be on the street they will get dirt and dust in them and be toast in short order, then you're replacing them every year or even more frequently.
The sphericals on my dedicated track car were sloppy after less than 2000 miles, and that's pretty good. Most race teams that use them expect them to be replaced annually. We replaced them on the Pro3 car annually. That car saw a Pro3 season plus once endurance race a year, and they were trash when they came out.
If yours last longer than a year with regular road use I will be VERY surprised. If you were up here where it rains sideways half the year, I'd be impressed if they lasted 4 months.
Just use high durometer poly throughout if you plan to drive it on the street.
The earlier mentioned Strongflex bushings are pretty damn good. The red ones are even tolerable on the street if you have really nice dampers.
