I just installed a 5.0 race tech spring 2 rides ago.I noticed the last 2 coils on the bottom are cutting grooves into each other.I can see that the eibach i had before had rub marks ,but not grooves.I guess when my suspension bottoms the 2 coils on the bottom are compressing into each other.Would this be considered normal.RACE SAG IS 95MM STATIC SAG IS 25MM.
