I've finished my xb4, although am undecided what to to with the pistons. Seems to be a few different variations. I noticed that both the base setups for clay and carpet both use the same pistons, along with Bayers EOS setup. Anyone have any opinions?

I will take a pic while i tear it down to clean. It took like 5 minutes and the feel was very noticable. I mostly run low to medium bite. It works awesome.

Did you remove the piece that's cut or does it stay put just cut for flex? Thanks for the help

I took it out. The aluminum chassis plate is already pocketed out to clear the ring gear so it makes it a super quick mod. I did it for a guy at the track in 2 minutes. Well worth it buddy.

Did you do anything different with the rear camber link mounts on the tower or hinge pin inserts? I also run on similar conditions and want to try this mod.

No, Everything comes down together. The whole rear end cluster. You will need to remove the 2mm carbon fiber shim from the front of the transmission housing by the drive shaft.

Some funny stuff on here!
On a side note $70.00 for aluminum shock caps
I was just checking to see what was avail because I picked my xb up previously loved, very clean and little run time, But I ran it saturday night for the first time and 2 of the four caps were weeping. I gave them a little snug up today so we'll see.
By the way, It did drive incredible! I got to the track early enough for about 20 laps of practice before racing and my first qual I was able to stay on pace w/the top 4 guy's. Soooo much fun!
I did finish off the wing that came w/it tho....This thing jumps like a gazelle!

they'll probably still leak...

2 methods you can do:

use a grease around the threads to help seal the leak or purchase shock cap orings

A pair of body scissors and an exacto. It came out very clean.

could you take a pic of your rear-end? (haha funny I know)

I want to see your modification to the hanger

I ran the car with the dropped gearbox and modified kit hangers on my slippy and it was excellent. Really helped lock in the rear of the car.

I've now got the new optional +2 hangers and they raise the mount points higher/closer to the outdrive by 2mm. really hoping this helps to lock in the rear end more on the slippy stuff with the dripped gearbox. Testing Sunday, will feedback.
Anyone else done this yet?
I knew I had seen the stock rear hanger mod already.
