as Honolulu says, there is a ton of info on this topic inside the search function. I recently went through this very thing though and can add that there appears to be fewer options now, for struts and shocks, unless of course, you just want Bilsteins, then you are all set. In my case I was looking for something not so firm, more like the Coupe rode when new. I discovered that the Boge/Sachs units are no longer available. Settled on adjustable Konis, I can install on soft setting and go from there. As for rear, I still have replacement KYBs on there, but unlike Honolulu, they have held up and I have no complaints. They too are getting hard to come by, so I guess bottom line, if you think you need new struts or rear shocks, start shopping now.
