Been running mine on the street for a few years. Nothing that I've ever considered worrisome. I can sort of tell when they release from the spring and then land again sometimes, but I drive pretty careful so that doesn't happen too often. Even then it's just a bit of a clunk. The biggest thing is the aluminum spring bushing. If you run that, which I do, you get more noise and "feel" transmitted into the car.

At some point you have to decide if you want a nice street musclecar, or a street/strip car. I personally embrace the racecar feel on the street. If I wanted a smooth ride, I'd jump in my Altima.
