I guess I never really explained why the coilovers were the better choice, eh?
First off: my race car is a 92 SL2. I happened to be in the right spot at the right time and picked up a set of the Koni DA struts with the coilover adapters (if you want to know more details, please e-mail me. I'm not certain I should broadcast all the details).
The reason the coilovers are recommended is for chassis setup. Being able to adjust the spring perch will let you adjust the corner weights of the car and help you tune the suspension more easily. Obviously, if your shock are also adjustable, this gives even more tuning capabilities.
Unfortunately, Koni doesn't make a strut for our cars. There are coilover kits, including the housings from Ground Effect (or is it Control, I don't remember) as well as Carrera. Neither of these are a perfect fit and each has their own special frustrations.
The KYB struts and H&R springs are OK, but if you go with the H&R race springs, the KYBs will be over-powered by the springs. I've personally run with the H&R sports and KYB struts on track and thought it was OK, but it was nowhere near the fast solution. These are now on my daily driver (93 SL2).
I'll try to take a look at my Koni's tonight to see if there is a model/part number on them. I'm fairly confident that these are off the shelf units, but I've never really bothered to look to see for certain. If you'd like pictures of that setup, just shoot me an e-mail and I'll send them along to you.
