AFAIK, the only significant difference is in the depth of the hub,
therefor the rotor hat depth you'll need. The S4 hub is slightly
deeper than 10V. Only way I know to tell is remove wheel and measure
hub (housing) depth. It's my understanding that most (all?) UFO-G60
conversions done at dealers under warranty were with S4 struts. There
could be exceptions I suppose. Sorry I can't recall the numbers (mm)
