Standard Sti Suspension Maintenance

[scholesy87]

Being a fan of cheap home maintenance i have recently seen a couple of videos (one from the states) about people who have installed grease nipples to the shock absorbers to overcome the knocking problem. As my shocks are nearing that point ive been wondering if anyone on here has done anything similar rather than just go to coilovers as i cant really afford them at the moment. The shocks should be easy enough to take apart and grease but not sure about drilling and tapping a thread in them.

Any help or advice appreciated
