The plastic ones are usually fine, mine's lasted 14 years so far.
The only time you'd likely have a problem is if tbe cooling system was over pressurizing for some reason (such as a faulty head gasket)

Mishimoto do all aluminum rads but not a direct fit for the Z3. It's thicker so you need to lose the viscous fan (either run with the aircon fan only or fit a slim electric to replace the viscous).
The standard rad is fine and only fail after 10-15yrs plus, mines 19yrs old and still fine but I think I'll change it soon along with plastic expansion tank just to be safe. Long enough life span really.

Zionsville Autosport radiators are the best, but they are not cheap.
