larger Pinion or smaller Pinion... Slower wear???

like i said in your other thread, the plastic spur is very thick and you should be very happy with it because as long as the gear mesh is good (a little tighter than steel spur) you should not have any problems with stripping it or breaking teeth. it is just weak enough to break on a really bad on-throttle landing and will protect your tranny from broken gears. i am still on my original plastic spur after 40 very hard runs.
