I ended up with 10k/80k/5k by the end of the night. I started with 7/100/3
Overall picked up .3-.4 on average fast lap over the slipper. Others results may vary, but for me it made the power deliver more smooth, sweepers and mod corner acceleration seemed improved as well.
Hoping to make a practice night this week to play with the fluids a little more.

see thats what i was thinking to but when i emailed xray and a team driver they both said 500,000 for med/high bite clay. I then asked " why so high, isnt that just like locking the slipper down, wouldnt we want to run close to what the d413 and b44 are running?" and they both replied back that the xray has much smaller gears then the b44 and d413 and that they are more smooth and not a rough so therefor you need higher diff weight. needless to say I ordered 500,000 300,000 200,000 and 100,000 since I have 70k in my bag. I figured if they were right i would want to have it and test from there...

The XB4 front and rear diffs have the same size internal gears as the center, so if the team drivers logic were to hold true, shouldn't we be running much higher front and rear diff oils than the B44.3 and D413 . . . like 40K front and 40K rear? Yet the Xray manual suggests 8K front and 8K rear which is right in line with the B44.3 and D413 . . . so I still think that 500K in the center would be waaay to tight. Are the team drivers you spoke to in Europe running on carpet tracks? I'm not doubting you in particular, I just can't buy the reasoning for their 500K to 1,000,000 recommendation.
the team driver was from Europe but he said he really liked 500,000 on clay there and 1,000,000 on carpet tracks. he also said he has gone as low as 300,000 or even 200,000 on looser dirt tracks. then Rc America said the same thing for med/high bite clay and they are from Texas.
I am on your line of thinking thats why I questioned both of them on this. it almost seemed like a misprint to me but hearing it from both them and the ppwk I put 500,000 in mine tongiht and will be testing tuesday night. Ill let you know as if its to high ill try 100,000 and then 70k if need be...

Running shorty setup and I found 500,000 to be in the ballpark. It worked great on our high-bite track, and if you really want some give to the middle diff you have the option of going lower.
i have initially settled on 3k front and 8k rear and this seems to work well on our track. Tried stock 8/8 which was ok, and also tried going much thicker front vs rear which made the car far too twitchy for me.

anyone know of a US site that has a center diff for sale? The one from Germany I ordered 2 weeks ago has gotten lost.
