Looking for more side bite. It "swings" a little to easy on throttle infield but still very controllable and drives better than anything else I've owned. Just don't want to chase setup and make to many changes. I'm sure its very simple because it's almost there.
Switch your set up to the Bayer euro champs.. and you will not have an issue with side bite or anything else. If your grip is low drop the diff weight to 5f/3r

+1 on the lighter diff oils. not just for lower traction but for smaller and tighter tracks too. if you have 180 turns around a singe tube then 5/3 can really get around the turn tightly and let you power out.
high bite clay I'm liking 7/5. black dirt with dust on top 5/3.
5-6' turn radius, 7/5, 2-3' turn radius 5/3.
obviously, you want to tune for the majority of the track.

Anyone got a '14 yet? Curious to know if they come with diff shims, the 2wd doesn't.

Had mine for nearly one month now and no shims since the bulkhead has been redesigned to minimize the shim problem.
It's fun that the 2wd manual tells how to shim diff, no similar step in the 4wd manual. I thought 2wd had the same new bulkhead?

Any issues during build?

Shimming has been discusssed ad nauseum, dimensional differences between the various gear versions have been given. According to some people here no shims are ever neccasary, ( then why did they change the parts? answer me that) however I believe that no matter what part we are discussing... shim if you feel it's needed. It won't be in some cases but may in others depending on your mix of parts. The bulkhead btw has no effect on shimming, that area is the same as the og part.

I had to shim the diff in the 2wd, never used a shim in the 4wd.

Absolutely no problem, the car is the same as the 2013 plus some interesting set-up possibility.

Thanks on diff and set up suggestions. Now that u say lighter front fluid, that makes sense, just a little to much on power steering is making it a handful.

The only Xray springs I have are the stock 2-dots front & rear. I use some TLR but mostly AE's 12mm. Apparently Avid spring sets fit as well. I also picked up the AE lower spring cup retainers as the AE springs are actually just slightly large in diameter then the Xray's, but they don't fall off the Xray spring cups so far.

Oils? I have switched to Core RC oils, they come in cst, so they match the Xray factory set ups - I have 300cst up to 700cst in 50 cst increments (I run outdoor clay and indoor carpet so I need a lot of oil!). Otherwise get AE oils if you can, 30wt to 45wt.

I tried running 7k front and 3k rear diff oils and didnt like it much. The car rotated too freely and was hard to correct on a dusty track. I went back to the 10k front and 5k rear and it calmed the rotation down and gave me back some on power steering. The car was just overall more smooth. Dropping the rear pins by cutting the plastic on the back of the chassis gave my car great rear bite. I settled on this for the tracks i run on. This is low to medium bite.

You can find this info for the XB4 in the downloads on Xray's website.

Downloads XB4

This may be helpful in making the pinion and gear last a bit longer if they are old and worn. It may be required for the newer metal gears coming some???
