You can fit the spring compressors before jacking up the car completely, saves you alot of hassle. I had to cut off the spring compressor bolts about 2 inches to use them on the Xedos. It is a PITA to get the fork over the lower suspension arm without compressing the spring like an inch. Do NOT work on the car without proper stands! May easily end up in the news without you being able to see it.
I recommend KYB GR2s, last longer than stock, at least mine do so far. I wouldn't install used shocks either, unless you know their milage is very low. And definitely not on one side only. Also change the dustcover/ bumpstop. They tend to detoriate faster than the second set of shocks, even the first actually.
