Since TCK's were mentioned above, my experience with the E36 plates is that they get noisy quickly and need new bearings often.
On my Vorshlag plates, I've had them for 2.5 years with ~25k miles (15k on 135i and 10k on M3) and they are just as quiet as when I installed them the first time. The bearing is very robust and reviews have always been stellar on these plates. My only wish is that I had waited a bit longer and gotten the aluminum version which is anodized red. I just like the red look.
