What do people like for 64-pitch pinions and spurs for carpet racing? I used to use some Titanium Racing pinions and some of the aluminum Robinson ones, but I can't find the ti ones anywhere and the Robinson ones seem to chip a lot, even indoors.

Any suggestions? Thanks!

I second that! Can't go wrong with the PRS stuff.

PRS gears are highly recomended I have not had any issues with them since I started using them.

RW Supalite Delrin spurs are pretty indestructible, i have one that's been frequently used just less than 3 years and it's still like new.
I like the Kawada alu pinions cause they're cheap

My PRS gears have been great! Highly recommended.

will PRS's "oval" gears work in bigdiff 12th cars?

Jmccormick

Yes they will I run the oval PRS gears in my CRC with the large d ring diff.

Thats a good question, why are people running 64 pitch gears?

64 pitch give you finer gearing changes/options to choose

I have had problems with PRS pinions. I have had 2 or 3 of them that did not fit on the output shaft. The ti racing pinions have been the best for me.

I like Kimbrough myself.

Smoother, and you can get closer to an 'ideal' rollout.

I've only ever used Xenon spurs and Xenon pinions aswell as Hirosaka pinons.

do you have the formula for rollout? Also what units to use for the measurments. I am confused because what make for a different gear ratio if you have a 72 tooth spur and its 64 or 48 pitch (doesn't it still have the same # of teeth?)
