So... Bottom line! I have the 22-4 2.0 and run a 13.5. It's a lot of fun to drive but a pain to work on. Do I buy the B64D? Is it better or just as good?
I have the B6D and love it. Please give me your thought on this 429.00 decision. thanks

Running 13.5 with that car should result in very little need to work on the car often.

I saw a bunch of the B64's run last week. I was very underwhelmed, but the car is still very new. I suppose setups will improve.

I tried mine with and without the Center Diff spur gear cover on and it rolls more free without the cover on. I think the screws are possibly tweaking the front (plastic) part of the center Diff mount and causing uneven pressure on the bearings and creating drag. Might be worth testing if you're not getting enough free roll

How are you running the car without the dif cover, what is holding the diff in place ?

Any body have problems with diffs leaking? Ran mine last night and when I got home I noticed diff fluid around the frt diff case.

Does you case have a hole in it?

I didn't say I was running it, merely rolling it without the pinion engaged

anyone try the shorter center brace yet? review?

Ok my mistake, wasn't criticizing just wanted to know if you had some special trick going on. I am willing to try almost anything. lol

Is that a common problem the cases having holes in them? I didn't notice anything when I put the diff fluid in.

Yeah, there's been people with one of 3 mold markings having a hole. I'd check that first. If you do have a hole a small set screw should fill it until AE sends you a new one.

Even though I initially was not going to get a B64D I got one anyway, I didn't really have to many issues with assembly, however it definitely does not drive like my 22 4 2.0, but still tweaking setup and generally like the car. Now to be fair the 22 4 2.0 i platform has been out a very long time and the 2.0 is a even more refined version, so naturally its going to be a more dialed car out of the box. The B64D is a new platform and just as any new platform there will be issues. YES even the EB 410 will most likely have some issues. Just the way it is. If you choose to purchase the first release of a new platform you should expect this, the only thing is how the manufacturer deals with issues and Associated is very good at rectifying issues.
If you want a car that hooks right up and drives amazing out of the box get the 22 4 2.0. If you are patient and willing to work and wait for setups and refinement of the product then get the new Associated , in time the B64D will be a great car for most instead of a few right now.

Another thing is people are always saying how hard the 22 4 is to work on. The 22 4 really hardly ever needs work unless you are a crappy builder. The front diff is a breeze, rear diff doe require the removal of rear tower but not that big of a deal and ..yes...spur gear change is intense, small price to pay for a great car.

It's a vent hole to prevent pressure buildup.

Appropriate avatar is appropriate....

Just a note for anyone running on turf, switching the center diff fluid from 100k to 500k made a huge difference in overall speed. My first few packs on 100k and the car was a slug, changed to 500k tonight and it was a rocket.
