This is Scale Dynamics V16D Work Equip 01 9mm Offset Rim 2 pcs Black For 1/10 RC Drift. The given off-set is based on Tamiya 0mm. This seems much, but please try to understand how this is calculated: the overall wheel width is roughly 29.5mm (this extra 3.5mm is for the stretched sidewall and outside rim) So the tire mounting position is 3.5mm more back. This makes you need the judge the off-set 3.5mm lower when you want to compare with other brands. So when Scale Dynamic gives you 10mm offset you can compare it with 6.5mm of other brands. But keep in mind this is based on the tire position. The wheel will stick out because of those cool stanced look.
For: 1/10 RC Drift
Offset: 9mm Offset (Backspace: 13mm)
