Not very good quality. The studs are way too long so you will need really deep lug nuts or open ended ones. Also the nuts that came with the spacer that hold the spacer on are pretty small/slim. Considering this piece of metal is holding your wheel on I think the nuts that hold it on should be of better size and quality. Compare these to H&R spacers and you will notice a big difference. Not sure I am putting these on. Could be a safety hazard.
