I've run the car for 4 meeting now and I've still got the kit ones in.

I've been told AS6581 ASSOCIATED DIFF BALLS 3/32 CARBIDE are the ones to use at only £12 for 12 from loads of places.

I've also seen some ceramic ones for 99p each somewhere with free delivery.

The Kyosho ones are about £17

Still not sure which ones to get though....

i put yokomo 3/32 diff balls in mine as i flat spotted the kit balls, changed them before the rings wore a groove, works fine, i think any 3/32 diff balls would fit.Question is who's got (makes) the hardest balls?

Acer Bearings do metric hard Carbide balls, and also, if you want to run the diff's a little looser then normal but not slip, just use some 1500grit wet and dry (Wet) on the diff plates, this will allow the balls not to slip on the plate, create a hradenned track and not square off your balls (ooeeer).

mad, never heard of that one steve.. had problems with diff slippage at batley on sunday, wonder if that might have helped me.

Basicaly, the smoother the surface you have, the easier it is for the balls to slip over the diff plate, when you 'scuff' the plate, it gives the balls more to grip to, so you can run the diff a little looser without the diff slipping, this also helps with wear on the plates, as the balls aren't being pushed into the plates.

The other big killer is to much grease on there, should be just enough to lubricate the balls, and no more, the thrust race, pack the bugger.
