The rear belt is sitting snug not too loose or tight. The rear arms don't move up and down freely because the out drives and diff are effecting being "pinned" by the drive shafts.

Has anyone else experienced this and if so how is it fixed?

Maybe you can check whether the right dogbone length is used. Yokomo front dogbone length is 46mm and the rear is 44mm. I did that mistake when i was building mine.

What do 1.1 3 hole pistons do and how do they compare to stock 1?

1.1mm is stock with the 14 kit.

1.1mm has less high speed dampening (pack) compared with the 1.0mm pistons.

My BD-7 will be arriving today I will be running 17.5 Blinky on carpet with a Tekin RS gen 1 and D4 "MAXZILLA" motor. I got my gearing somewhat sorted out for the track I will be running at (FDR 3.6 to 4.0). My question is what is a good range of motor timing to set and what C rating and Mah should I be looking for in my batteries? I was thinking something around 70C and 6000mah, but not sure. I am a club racer, doing indoor carpet to keep a TX in my hand this winter.
I haven't run touring or carpet since the Corally RDX first came out

How do measure if the left shocks are harder than the right, measure the ride height of the left and right side at the middle of the chassis? Adjust till equal

You adjust and set equal preload by:

1) building all 4 or pairs (front & rear) of shocks to equal length.
2) turn the shock adjuster nut equal amount of turns to ensure that both shocks (L+R) have equal preload. The way my shocks are built it's generally 2 1/4 turns for Pinks in front and 2 1/2 turns for Blues in rear.

Ride height is generally measured at the 4 corners of the chassis. If there is a difference L to R on either the front and/or rear, then you'll want to check on the following.

1) chassis tweak
2) distribution of weight on the chassis
3) shock towers/bulk heads tweak
4) setup board flatness
5) springs

My son hasn't had any issues with his bit I've heard the steering blocks and hubs are fragile on carpet where they meet the boards more often. Haha. Shaving the axles will probably help with that.

Rear arms are same length, only shock location is different with option hole location

Kit is 4* caster
