I've been told that KYB shocks are very stiff. Some folk like them, we will see since I got a set for the front of the 280 SE for cheap on eBay. If I don't like them, the originals go back in.
I also bought a set of used shocks for the rear. Unless they are completely gone, the will be better than the Monroe Gasmatics (or whatever) that are back there. Too much gas pressure (the rear sits up too high) and so stiff you'd think they were solid.
