What Spur gears do you guys use ? Myself & my son have gone through 4 spur gears this year. I want something tougher than the Spec R ones. They're also quite coarse which produces noise, therefore more resistance which means power loss. My car has noise whereas others are quiet and smoother.
On the subject of turnbuckles, I installed Lunsford titanium ones on our cars and they're great. I don't have to keep checking to see if they're bent.
