2 Jacks, or a jack and a jack stand, set of sockets, spring compressor, and patience. I've installed them on 3 cobras with IRS and it was not that bad of an install. I've heard the solid rear is much easier.
You need Big metric sockets to get the lower strut bolts out I did not use a spring compressor, I have 4 jack stands and used the 3ton jack to lower the arms enough to get the springs out in front. In the rear you will have to take the Quad shocks off to get enough drop to get the springs out. Just be real carefull ,stand out of the way in case the spring wants to fly out. A buddy and I had it done in an evening.
