Review on Dorman 930 550 Wheel Hub by Todd Taniguchi

Ordered two of these bearings for my 1991 Mazda Miata. I was hoping for Taiwan made versions but instead got two Chinese made versions. Details look good. Cleanly processed, no burrs on the teeth. I'll install them soon. I am installing ARP wheel studs and am nervous about which part number to order. Some threads on the Miata forums have mentioned that all replacement hubs are made with Miata roller diameters larger than 94. I pressed the standard wheel studs onto these Dorman hubs and measured the bore diameter which was .550". They appear to have a 94+ knurl diameter since the bolts they contained had a .570" knurl diameter. So I'm glad I ordered an ARP PN 100-7720 with the correct knurled later model (.579") for them, not PN 100-7719 with a 90-93 (.515") knurl. However, ARP 100-7719 studs fit my car's front wheel hubs. Hope this helps someone!
