yeah, now that you mention it, I have heard of the rear block breaking. Didnt really hear of broken rear hubs. Is the material just to thin around the hinge pin? My 8 year old would be driving this car probably also....So it need to be able to eat pipes and role over crash, lol.
I wouldn't waste this car on an 8yr old. Give her the b4 or te 22. no parts needed other than stock. Amazing huh?

Need a little help here.
Just finished the build and was wondering how tight should the diff nut be? When I spin the tires in different directions at the same time (one going forward the other going backwards) the tires rotate 1.5 turns before stoping.
Is this tight enough before I start the diff break in?

RB6 Setup
I know mid motor is super hot right now, but I've been working on a setup for the rear motor RB6 that uses ALL RB6 PARTS. I'm tired of buying old gen car parts to put on my new car so I came up with this with the help of my buddy Shaun.
I don't feel that the 521-1 are faster than the RB6 arms...maybe they feel easier to drive, but slower on the clock for the most part.
Try the whole setup and let me know what you guys think. Adjust ballstud washers accordingly to your tire and grip level. Rear shock length is off the top of my head, but basically all the way up with the longest shock bottom.
Feel free to ask questions if you have em.

What are the part numbers for the mid motor config aluminum arm carriers?

Break in
1/2 turn
Break in
1/2 turn
etc... etc.. until the diff is where you want it. Once it's set (tight enough so it doesn't slip). Run the car for a half pack or so, and recheck... usually needs another 1/16th turn or so after driving the car. (if memory serves)
YMMV

After trying multiple ways of building ball diffs the best way I've found by far is:
Use 220 grit sandpaper wet with WD-40 on drive rings. Polish them until perfectly smooth and even. They will appear scratched but this is what you want. Use a piece of glass to keep sandpaper flat.
Build diff with plenty of grease.
Tighten diff beyond what you would want for ideal driving setting by half a turn or so with the slipper a little loose
Run half a battery then loosen diff to normal race setting and tighten slipper to appropriate setting
Using this method I have had my ball diffs last for months of use and they stay silky smooth. I've even taken them apart just to add grease and reassemble without new parts because they lasted so long.

The plastic part is fine as long as you use the plastic inserts. The metal inserts wear out the plastic susp holders really fast and within a few packs you get a-arm slop.

Thomas,
I switched to a similar setup last week.(Dunlap helped me out) Anyway its about 95% the same as your current setup. This setup is better (for me) than the one using rb5 arms, I feel its more consistant.
So if any of you want to try Trans setup... I would. 3 of us at our local track have switched to it from the TEBO variation and pefer it.
Some asked about the plastic sus holders, They are suppose to provide more flex than the alum. I switced to those about month ago with no issues of breaking. I will switch to plastic inserts though.
Anyway T if you get a chance come down to NW and run with us!! Hit up Shawn he has been down quite a bit.
