black star = u.s. OEM stock
pink star = 22B
pink I = sti
rabbit = not a grill badge at all. it's acually a sticker that went on the SIDES of some of the sti's... someone decided a bit ago to place one in place of the OEM badge on the front grill.. so there you go!
there is also the green "I" badge... a variant of the Sti badge...
