I was doing a service on my forks today when I found a broken free piston on the left fork. It split from top to bottom and kinda spider webbed. I've searched around and found other threads that talk about the modification that smart performance has, but am unsure of the exact details. How does this effect the handling? What are the pro's about this modification and are there any con's? I've also read about aluminum replacements. Does any one know where I can find them online?
