So I've been searching through the forum and other sites on how to go about installing DC5 coilovers on a Ep3. People are saying to shave the rear bushing of the coilover so it'll fit and others are saying to drill. Am I making the diameter of the bushing bigger or am I grinding the bushing down, or am I drilling the hole where the bushing sits in? I've read that 3mm is the magic number. I'm new to this so sorry for any inconvenience.

EDIT* I know that I need to get the RSX tie rod ends for the front.
