I changed because all the cool kids did it…. Honestly it was just one of those things we looked at and thought of as a very good safety upgrade as we entered the mid 9 zone. Pretty cheap protection considering the catastrophic damage that can result from breakage. It should have been done when my dad had the S60 built, but was probably an over-site. Kind of like a billet drum in a 727…. Pretty cheap insurance in the scope of the mayhem that can incur….
