Mine keeps swelling after a few track days making removal difficult. Starting to get a collection over the years of perfect condition pins with swollen rubbers in the shed. And it seems wasteful and isn't exactly cheap to replace the whole pin.
Alternatively, does anyone run the NB upper "rubber-less" pin in the lower position as well? I'm assuming the rubber is only to stop rattles, but if the top pin is rubberless and doesn't rattle then why would the bottom? Seems quite a few other brand cars run both slide pins without rubber sleeves.
