Is it because everyone wants a bit of a lift with the 5100s? That people who don't want to lift are satisfied with the OEM Tokicos? That the 4600s aren't that much better than the Tokicos? Just curious. I don't want to swap out the UCAs until I'm out of warranty so I'm going to wait on the lift. But that doesn't mean I can't look for ways to improve the stock suspension (or just spend money...)
