Good call on the crank sensor and other parts, but also think about what you'd need if you needed to fit any of those parts yourself, ie: portable trolley or bottle jack, 2x axle stands and the required allen key or bit required to do the crank sensor. Plus a selection of spanners and/or 1/4" socket set, including 19mm socket plus short extension for wheel bolts. Other allen keys/bits eg: to remove cam covers and coil packs. Spark plug socket maybe and spare spark plugs?
As well as oil, bring some anti-freeze/water mix, and as well as hose clips, bring a selection of spare coolant hoses, eg: thermostat to rad, CHOD, etc. Consider a spare set of front brake pads if tackling any alpine passes or race tracks en route (plus tools including a suitable drift for the pad retaining pins). And a torque wrench will come in handy for checking wheel bolts etc.
And if you have a fault code reader, bring that too.
