The reason to replace multi-link componentry is not because stock links will fail, but rather because stock links have crappy rubber bushings which, at the age they are at, will deflect CONSIDERABLY under cornering load. Once you're deflecting your bushings, you are allowing your effective link length to change, meaning your suspension has poor wheel control under load. This allows dynamic toe and camber change with load, negatively effecting your contact patch geometry, and thereby reducing traction.
Almost all aftermarket links come with spherical or heim joints, completely eliminating bushing deflection and dynamic toe and camber issues, giving your car a more "solid" or "connected" feel, and serving to increase your confidence as a driver as well as your ultimate grip.
SPL arms are nice, but they are definitely not the best. I have SPL RUCAs and after about 6 months, the surface coating started flaking off and the arms started to rust. They are, however, very lightweight, and will reward you if you take care of them (clean them, apply anti-seize to adjustment threads, etc.)
