I ran the same set of cut gears for 1.5 years with no issues in the b6. However, I never run a lockout. I set my slipper tight but it has a little give for on power lands and will slip if you catch a tube and don't let off the throttle quickly.......Maybe the new gearbox with the shims to raise/lower the diff isn't as forgiving or have quite as precise a mesh as the b5/b6 locked diff design? Is that gear smoked or just covered with grease? Cant tell from pic.

Running in carpet... Been having troubles in 180 deg corners. My outer rear tire lifts up . I have the kit setup except I have 40wt all around, ride height 15.5mm rear and 16mm in front, 7K with 2 gears in transmission, and running a lockout. I run with drag brakes to slow down in corners . Any help is appreciated.

The rear oil seems pretty heavy and perhaps restricting the rear end roll. I would try dropping it to 30wt and see if the rear rolls more so it matches the front.

Question about the front axle height options that come in the kit. It has 4 bushings, two per side. What are the two options for these? I have the thinner on the bottom. Is that the same as +1 or +2 on the setup sheet? It looks like the thinner one is 2mm so I believe it is +2. Just trying to make sure I am correct. To get +1 I would have to use shims or get the Schelle kit correct?

I have the B6 bushing set but it looks like my only option to drop the axle is a 0 on the bottom, it is very thin. I was trying to follow the recommendations for axle height settings for 21-22mm ride height. It is weird because the listing for this bushing set says there is an option for +1 but I do not see how that would be possible.

Thank you that helps.

So the B6.1d kit did (at least mine) come with the 2mm and the 1mm. So I do have the +1 setup with the thinner one on the bottom. Kit setup sheet says the kit setup is +2 but the instructions tell you to put the thinner at the bottom which would be +1 which is why I am confused.

Great post, but this is a bit off:
"They have a massive downward angle, and you’ve effectively raised your roll center a bunch."

If you only angle the upper link like that, it does raise the roll center. However, angling both the upper link and lower (a-arm) as you pictured by compressing the suspension produces a much lower roll center vs the fist picture where the arms are level.

Default Diff Binding

Has anyone had an issue with their gear diff binding? My transmission spins freely but when I drop the diff in it seems like it's catching or rubbing on something. I've ran it a few times without any issues and pulled it apart after running but cannot figure out what is causing the binding. At first I thought maybe the diff screws were rubbing on the inside of the case but I don't think that's it. I'm starting to wonder if the diff or idler gear are slightly out of shape.

Check the Diff height bushings for rough spots/flashing. If they don't sit in the transmission case perfectly, the diff goes in crooked and will bind

Here you go. I mocked this up quickly in CAD. It's not to scale. The only thing that matters is the relative distances. The top is the low axle height at arms level. The middle is a high axle height at arms level. The bottom is the low axle height but this time with the chassis lowered to the same ride height as the middle.

Perfect! Your mockup also displays how camber is altered between them and is a good reminder that changes in ride height affect other settings.

Can anyone tell me the number of teeth on the top shaft gear?

Pretty sure it is 20 teeth. The diff has 52 teeth and the transmission ratio is 2.6:1, so 52/2.6=20.
