i just started using the clear grooved o-rings. They feel great but haven't run them long enough to really make a good opinion on them.

I run the blue x-rings from traxxas. Work great, last forever, painfully cheap.

This was reported earlier: Kyosho have discontinued the hubs and will be releasing V2 hubs in 0 deg (and 0.5 deg). Cheers,

I usually run the ORG03X (clear) x-rings.

You can also run the ORG03XR (red) x-rings but the clear are a little better.

Traxxas is "The Fastest Name in Radio Control" so I can see how traxxas x-rings will make the kyosho faster I have been using the clear kyosho x-rings and they work great but also the stock o-rings work good as well, kyosho shocks are great.

Carl's bulkhead is the [email protected]#$ had one on mine for a while settled the rear a little and you can get to the ball studs without taking the tower off his front brace is a lot stronger too highly recommended
