Will fitting this spur change my gear mesh settings?

A new spur can alter mesh slightly; always set mesh after fitting and check for smooth rotation under motor torque.

What pinion should I try for longer straights?

Try larger pinions in the 40T to 45T range to raise top speed, but monitor motor and ESC temperatures when doing so.

How often should I inspect the spur?

Inspect teeth and mounting points regularly, especially after impacts; replace if you see wear or deformation to avoid drivetrain issues.
