I need help identifying these rims. I was only told they were for an RX-7, but I haven't been able to figure out who the manufacturer is or what year they might be for. The person who gave them to me came from Japan, and may have purchased them there.

Any help is appreciated.

 

Those are factory wheels that came on the 93-95 US spec and I believe came on the 93-96 Japanese spec 3rd Generation Mazda RX-7
The bolt pattern is 114.3x5
The wheels are 16x8 all around with a +50 offset. They are an extremely light cast aluminum that weighs just about 15lbs each. These are some of the lightest OEM wheels made and a lot of Mitsubishi Evo guys buy these RX-7 wheels for their track wheels.

 

Thank you very much.

 

the UM is the manufacturer marking, U mold.

 

Thank you for that info as well. I was wondering about that.

 

the FD catalog doesn't spell it out, but the Mazda 3 has different part numbers for different wheel manufacturers. one of them, U mold, has that familiar UM symbol. the other two are hitachi which is an H, and Lio Fung which is like an H in an oval. there is also NF die casting, which has an NF, and enkei which has its sideways figure 8 thing.

the FD wheels seem to primarily UM

some special models wear BBS's, but those are obvious
