DA-OFM-V1S Offset master V1 set
Drift ART - OFM - Offset Master
OFM can effectively reduce the offset of the hubs (rims/wheels), such as reducing the +1.5mm hub to +0mm or -0.5mm.
Smaller offsets can not only improve the simulation of the car, but also fit more car shells, making it not easy for the tires to scratch the car shell. If you are using a hub of +1mm or more, the OFM can provide a good effect of reducing the offset value. If you just want to use +0mm hubs, this option doesn't offer a clear change.
