Matt,

on all four caps just drill a small hole, approx a #55 size hole or a bit larger. Clean out the cap and then glue to o-rings together and then glue them inside the cap, making sure not to block the hole. Then build your shocks with full rebound.

For me and talking with Adam it helps keep the shocks more consistent with the full rebound build. The more rebound the better on slick tracks o this works well, the higher bite the track the less rebound from what Adam told me.

I run it all the time, however I don't get the chance to hit a super high bite track often.
