If so, your engine should be fine. Everything after the engine (clutch, transmission, drive shaft, etc..) could be the reason. Seems like some imbalance somewhere is coincident with the resonance. Since the OEM wheels are smooth as butter, maybe it's your aftermarket wheels/tires/spacers.
Anyway, unless the aftermarket parts are from a top tier OEM supplier with high Quality Control standards, ALWAYS stick with OEM.
Wheels are Gramlights, tires are Michelin PSS, hubcentric rings are Muteki. Muteki is the only brand I don't know. Gramlights aren't an OEM supplier but definitely a top tier manufacturer. This also has started recently and haven't smacked the wheels at all to throw them out of shape.
