Looks like kyosho is coming out with a new chassis for the zx6. It will move the motor forward. I saw a pic in a Japanese website and looking at it I think it will give a future option for a center diff. The milled out area looks a lot bigger. Part number law54

And the bumps teen is crazy even with 2mm spacer..help!
I don't know of to many people using the gear diff on this car. Now I am not saying that is causing everything you are experiencing but if the drive train is not working properly it could cause the car to do these things and thus putting stress on other components.

My suggestion, go back to the ball diffs for now and see if the problems continue. Make sure you didn't bend any shock shafts as well. In addition, don't be afraid to ask someone else to look it over as a second set of eyes to see if there is something that you might have overlooked.

They don't need to come out with a whole new model to introduce new concepts, they just keep upgrading the car already out. I appreciate that.

Never thought of that, but could def be interesting. I prefer the ball diffs in the car. Can't wait to get the chassis

The center diff really smoothies out the drivetrain and saves ball diffs. xB4 owners in the area have done the mod and love it as well.

I'm running on med bite clay indoor (small technical track with one large jump) and low- med bite outdoor (large fast track with several large jumps )

Ya I'm gonna try the ball diffs and see if I can't get a handle on this thing. I was really hoping that the gear diffs would help as I drive my mp9 like a bat outta hell. That and I have next to zero experience with ball diffs. I've had a few people look at my zx6 d they don't see anything built wrong but they trip on the bump steer and how stiff the suspension is. Thanks Kraig

Chriso138, I was running tebo's surf city setup which had 40wt in the front. The handling was released sketchy. I race on a high traction, clay, small technical track. I went to 35wt oil in the front and it was a lot better.

What I have found with Tebos high grip setups is that he likes his shock packages pretty heavy. Usually going down a half to a full weight gets me where I need to be.

There is no quick answer to that ProfessorX. You will have to use a combination of the silver (thick) and gold (thin) shims to properly shim your diff. You need to pay attention to the mesh with the pinion and the amount of side to side play. Ideally you want a tiny amount of play in the gear mesh (action should still feel smooth), and a snug fit in the gear case with no side to side play so that the gear mesh cannot change on you.
