Just put the new light weight pn 64 pitch carbon diff on my mr03 and the car is so much faster, smoother and noticeably quieter.
I was using a ball diff before (unknown blue diff) and didn't think this upgrade would be so dramatic

Combination of new parts + smaller pitch (more efficient) + MUCH lighter weight. Feels good man. ;)
I was just swinging by to see opinions on this diff vs Kyosho ball diff...looks like I have my answer :)
How is it with holding settings? Just looking at the adjustment knob doesn't inspire a ton of confidence.

The PN adjusting nut is delrin and fits snugly. I haven't had a problem with it moving at all, even on my mod car.

only problem i have with the pn diff is the plates they use. they are way to soft. normally i run the stock plates until the diff needs a rebuild then i replace them with kyosho plates.
Good to hear, may be picking one up this weekend then :)

On the ones i have the delrin nut holds better than any alum nut i have seen. When this diff came out, the description said that the delrin nut was harder to lose. I guess that meant it fit more snugly by design.

Don't think you'll be disappointed ;)

I haven't adjusted it after the initial dialing in of the setting. I've been through about 8 to 10 sets of batteries through it and my pn70t
I will post some pics of it and the diff I replaced.
I used the old baal did to upgrade my sons mr02 from gear to ball.

I've found that the adjustment nut is a bit soft when adjusting it. I stick the wrench in the hole (heh) and turn the left wheel to tighten/loosten and the hole seems to stretch out (heh) making it harder to adjust in the future. The nut does hold pretty well though.
Picked one of these up at the race this weekend. I had a hard time feeling a huge difference due to the fact we were running an HFAY layout and I was dealing with understeer after having to replace my front tires (which worked AMAZINGLY on my set up but are no longer produced :mad:)
It definitely did seem to be exiting corners much more efficiently/strongly. Actually made me have to adjust my throttle application on exit somewhat.
One thing I definitely noticed was that my car, which had previously been the quietest at our club, actually seemed to get even quieter :P

Chad, is that with the PN V3 Pressure Plate or the V2? :)
