Ordered the f-sport trident wheels from houseoflexus.com (better price than Sewell) for $614 ($642 after shipping)
After some searching, found a post on here that says the lug nuts are really rebranded McGards:
Ordered the McGards off of Amazon for $96 shipped with prime, so that saved me about another $50 from Sewell. They won't have the Lexus logo but big deal.
Hopefully get these installed next week or so after I receive them.
So i'm looking at around $740 total, not bad. Going to re-use the stock tires and it will be free mounting/balancing since my buddy owns a tire shop. Wanted to go with Enkei RPF1's for lightness, but I couldn't find anything near the $153 per wheel I was getting the tridents for.
