When my rears were taken off, and they're long springs, they weren't compressed at all. A metre long pry bar was used by one guy with his right hand while he pulled the strut with his left. It looked very easy, much easier than when I had the Eibach Spring compressed to dangerous levels and a spreader pushing the arm down..
I think it's worth ordering new bolts for the front and back, my front bolts had reacted and effectively welded to the aluminium fork, took me an age to get them out. Rear bolts were in the wrong way around, so I cut them off.
The front damper can get stuck in the aluminium fork too, so a few days before the work, maybe get some wd40 in there or I think it's a mix of nail polish remover with acetone and gear oil that's good for dismantling.
