I did with mine, I like it, but I dont know if 10f/10r would be better as i have not tried it. I figured for 13.5 I would not have a big problem with diffing out.

Good call, I think that will work great for your application.

Diff build tips. I recommend not putting any black grease on the diff pinion per instructions prior to setting up your diff as you can put the grease in from the bottom, not only less messy but the grease makes it difficult to determine if you have a slight amount of backlash (diff pinion and ring mesh should not be bound and touching at all times a little play is good). Additionally if you do have a sticking/binding at some point in diff rotation once the diff carrier is "clam-shelled" together, slowly rotate to find the bind and either mark the ring gear or keep your finger at 180Deg opposite the bind at the pinion, disassemble the diff carrier halves and tighten the screw near your mark on the ring gear and it should square up removing the bind. Check that the other screws are snug as well on the ring gear. Everyone should be able to achieve a "butter" diff. The little things make the difference and take time and patience. Between filling the diffs and waiting for silicone to settle, putting a dab of black grease on your fingers and coating both sides of the gasket and the proper shimming of the diff you should be able to build a perfect feeling and long lasting diff.

I also used a smidge of black grease on all screws penetrating the diff housing as it is a harder material (the instructions note this for mounting the housing to the chassis in subsequent steps). If you are getting squeaking of your screws as you are tightening them down, stop back them out and grease them slightly. This will make future maintenance easier and is less hard on all the hardware in the long run.

i got my b64 coming in soon
can't wait!

Yep... the diff housings are super tight when it comes to the screws.... which is a good thing. A 3mm tap is your friend. Such a great build so far. I was "coached" a little and went with a 0-7 shim package too....

Yeah having a tap to start those threads really made the build easy.

Sorry. Ignore this post. I was thinking of my XB4 with a slipper center diff. When I checked my gear Diff XB4, it does not spin as freely. Complete brain fart on my part today.

I have this kit built to completion as a roller. When I spin the center diff should I expect any free spinning of the front and back driveshafts? I am used to my XB4, and as a roller, when you spin that Center diff, everything free spins really nicely, and some serious free spinning. I just checked everything for binding, took apart the diff assemblies, and everything appears to be fine without any binding. Any input? Thanks in advance!

What front wheels are you guys using with the jconcepts 2.2 tires to get them to fit the b64d any help is appreciated

The standard AE wheel for this car works just fine as well as tlr fronts. Not sure on any others

You mean the ones for the 22-4 don't they have different offsets

How about the 60mm tires are there rims for those

ASC91575

Anyone mounting 31mm shock bodies in the rear?
