[Correction]: The SPC pivots are NOT rigid. For UCAs, SPC wraps the Xaxis joints in rubber, which gives them vibration dampening. This in turns reduces some stiffness. So in terms of bushing deflection, SPC probably sits right in between AccuTune and Ironman. Thanks to viewer Christopher Wilson for pointing this out.
