I have just done this job myself on my 1999 C2. I can agree that it is really satisfying, fairly simple and saves a considerable amount of money. I was nervous about the caliper bolts binding (having heard it mentioned in a number of articles) but had no problems (apparently it is fairly easy to tell if there is a problem, once broken the bolts will loosen easily by hand within a turn or two- if it doesn't stop). The only problem I had was one of the handbrake retaining springs had snapped causing the plate to jam the disc. Having tried brute force (which you shouldn't need otherwise) I noticed two threaded holes on the disc. I screwed in two bolts and was able to draw the disc off at the right angle fairly easily. You can get any spares from Design 911 or porscheshop. Without this back end would have been done in 2 hrs.
Otherwise it is just a case of safely jacking the car (with a jack that will fit as the points are fairly low - Clarks racing jack or a piece of wood under wheel, budget depending).
It is a good opportunity (especially at this time of year) to waxoyl the wheel arches and underside and treat the rubbers. Remember to fit new caliper bolts.
I really enjoyed it, have fun.
