Yeah I know Jay,

Seems that most are of the guys locally are opting for the 1.3-4 hole pistons. Say the car is way better with them. I think Mike said he has the Ghea ones. Not sure how many run the tapered ones though. I'll get it dialed in.

It's hard to get the right amount of pack with more than 4 holes in my opinion. Especially when we have circus jumps on some tracks.

I tried the 1.4/3 hole tapered and didnt like them. I keep going back to the 4/55 pitons I drilled from blanks. Been running 35/30 oil and AE brown front black rear springs. Car feels really planted especially on this off camber turn we have. Everyone else seems to slide down the side of it while turning and my RB6 is glued.

I found that the AVID 1.3 is the same as the 4 55
As for what I am needing is anyone using the V2 rear hubs yet ? I just put a set on my car and seems like there is not much room for the wheel nut now did I do something wrong?I have tried taking out the brass washer in center still not enough bite take a look and let me know what you think.

1.3 = 55 hole.. more or less. 1.3x4 was the way I went. Ghea tapers. I believe I went with the same oil / pistons / springs that's listed on Tebo's 2013 Midwest Winterchamps setup from CRCRC. It was pretty good. I would start with that setup and adjust off it.

The inner hub bearing doesn't look seated to me... maybe it's just the picture??

That is close to the set up I am running but I am running Luke Richards really close.
And yes it is all the way in for sure! I changed rims they bite more but not as much as I would like there to be!

Well it seems that the 1mm spacer that I am missing is the UM505B..the question is should I put it inside the hub or outside?

It looks like your bearing are not in correctly. Make sure you have the correct black plastic piece installed for your bearing size, brass piece goes inside hub between bearings

Paintchip, your exposed axles look normal, which means your bearing seating is just fine. You should have 1mm of un-threaded axle showing, and about 11 threads... which you do. Which means you have an issue with your wheel. I doubt your hex is seating all the way into the wheel (that's a kyosho wheel right?.. if not, make the switch). It's the only thing it could be.
