Actually, the Tracer headlight brackets are slightly different where the grill pops in, but as long as you use the accompanying Tracer grill, it is not a problem. The Tracer grill´s "legs" reach farther back toward the radiator, so the headlight bracket attachments are "flatter."
On the subject of headlights, I am absolutely diggin´ my BMW units. Man, the difference between these and the stockers is, pardon the pun, night and day. In combination with my Camaro high beam driving lights, I have some candlepower. YEAH!!
