I haven't trimmed them yet. the back isn't a problem,its the front that i don't want to cut. the front bumpstop and boot are one piece. the bumpstop is on top and the boot on the bottom. I was told to cut the bottom half of the bumpstop and the boot off. reason being, The top section(bumpstop) has a smaller hole to fit tightly over the struts piston and holds it in place. I don't want to cut the boot off because the shock will be exposed water/dirt,ect. If i just left the lower section with the boot on,it would lay all the way at the bottom,exposing the piston above it. so,either way,its not going to work.
