what is it, and what's it for? anyone know? thanks in advance.

Its generally to adjust camber....some but very few can adjust for caster too....but that involves another plate

pillowball upper mounts are more rigid than conventional rubber uppermounts which flex more. like the tein super street coilovers, though great suspension upgrades, aren't as great as the tein type flex coilovers.

so, on an xA or xB, is that something thats worth spending for..or no?

i wouldn't really see a reason to. i tracked an integra with some buddies of mine a couple years back and when we swapped out the skunk2/tokiko (springs/shocks) with tein type ra and what a difference the car made on the track. unless you've got money to just throw away. it'll serve much better use as a paper weight than it would to the scion... unless your gonna track the car :D

i figured as much.....thanks for the info :)

it gives room to better adjust your camber. Plus it is stronger mounts than factory.

oh... i think they can adjust toe and caster... but don't quote me on that one... yet.
