Camber bolts.
Option 1: OE camber bolt is a small (14mm) bolt in the upper hole to replace the big one, push hub in, tighten, bit sloppy but cheap and legal for certain classification systems
Option 2: Look up camber bolts, every company sells you a 16mm eccentric bolt for the upper hole, this works, I got about an extra -1 degree out of it. I believe more adjustability comes from buying a 14mm eccentric bolt and putting it in the lower hole then taking the bolt that was in the lower hole and putting it in the upper hole. You can also buy both eccentric bolts and install both.
