the rksport coil-overs?

hey does any one know if the rksport coil-over set is worth the buy? On the instructions you have to cut around on the strut and get ride of the lower pirch .... doesn't sound safe to be haking, and hammering at an explosive shock .... my friend has it he said it wasn't that hard to do but ya hes a little insane. help me out and possible save my life ...

Just be careful to not cut the cylander. If there is no spring on the perch at the time all you have to worry about it some fluid leakage if you F-up and cut the tube. Lets hope you don't.
