Maybe that setting talks about the hole positioning for the caster block insert.

Anyone else experience this yet?
hey Chad if your racing on Saturday come see Troy or myself. We are running triads and can help.

I had the same confusion when I first read the editable setup sheet. Are they talking about the position of the block? or the position of the hole? The sheet says "block position"... which certainly doesn't mean the hole (at least I wouldn't think so)... which is why I annotated such on my setup sheet

Default GHEA Pistons

Okay, I got my hands on some 1.3mm x 4 hole GHEA black delrin pistons. They came with no directions. My question would be which way do the pistons go on the shock shaft. My guess is that the tapered side would be facing away from the threaded end. But when I guess, I usually get it 180 degrees wrong.

Taper down I would think would make the most since, creating better pack for bigger jumps

When you say tapered side down, I am assuming with the vehicle assembled the taper facing down towards the ground.
