I see BONOSS wheel spacers have many new features, such as knurling, disassembly grooves, active cooling grooves.
Is there any quality difference between H&R wheel spacers and BONOSS forged active cooling wheel spacers?

 

Almost 12 months later, hopefully I'm not wasting my time here.

Couldn't find very much on the manufacturing process for these two different brands but from what I understand they both use different materials and different processes to construct their products.

From the little info I could find, BONOSS forges their spacers which tends to have stronger construction and durability. H&R boasts lightweight material and anodized finish. Both brands claim perfect fit. Really is up to you. If I had to flip a coin I'd go with BONOSS.
