If SPF are set up as MKI,II,III and IV a fairly good way to remember is "tight ass" or hit 12 oclock ear towards rear (on either side) to remove. To be honest, I still have to think about it every time I remove one. You might consider a thorough cleaning of male and female threads at each wheel removal and very very liberal use of anti seize. Realistic tightening and safety wire each ear so that it is prevented from turning toward the front (12 oclock ear) on each side.
