I run my RS 4 cab through a top quality automatic wash all the time, with no rim damage, at least not yet. I trust the place, have never had problems, and the track has plastic to protect the rim. The P Zero tires also have just enough of a chine to protect against direct contact. You all probably think it's heresy, but this car is my daily driver, this particular car wash is convenient to me, and I have to admit that I just don't feel like taking the time to hand wash it.
