Good fit
Quality seems very good and well packaged. 45 mm was perfect with 15mm spacers on my wheels alowing 13 turns on each. They seem to be painted, so we will see about durability over time.

Works. Finish is a bit garbage.
Functionally fine. The finish will basically come off if you drop them, or use a wrench on them. It’s a tough task, but I think it could be better. I wouldn’t expect them to look great after a winter of salt and sand, but if you want to keep your wheel on your car, it’ll do that fine.

Show Quality
It’s so great to see that they have taken the time to individually wrap each of these studs to protect the show quality finish. Likely done with an expired spray can of bbq paint off the discounted price shelf of a small town dollar store. I don’t blame that for the finish tho, or the 7 year old that did the painting. It was probably just poor lighting in the shed or something. Anyways these studs are the perfect accent to those custom wheels you just spent your hard earned money on. Whether they are black or silver or even chrome wheels these studs have all the bases covered! I can’t however comment on the grade of these bolts yet. If I go to leave the driveway and my rear wheels pass me I’ll let you know.
