With 58k miles on the tach, I figure it's time to replace the RSMs. I came across a guy who's looking to get rid of his used (~15k miles) e46 RSMs with the Z4 reinforcement plates for next to nothing. He has an upgraded suspension and decided to swap out the e46s for GC RSMs. Is there enough life left in these to justify me putting them in my car or would I be better off just getting some new ones?
