Rods talking about our new adjustable control arm.
It uses a slotted upper shaft with slugs to allow more caster to be added to the upper arm just by swapping out the slugs.
It is also offset, so rotating it provides more or less camber.
It has self lubricating Delrin bushings (no need to lube).
There's also a nice feature built into the shaft and bushings that "locks" the control arm in place (under extreme braking the control arm will try to pull the arm away from the bushing. locking it in prevents this.)
You can see a pretty good shot of it here:
