The fronts are only 26mm with 0° offset and the rears are 31s on 6° offset, and no spacers are needed for any electric car. You can't run the wheels/tires any other way—it's mandatory that you run narrow 26mm tires up front and the wide 6° offsets in the rear for all cars. The bodies fit perfectly on just about every chassis, and look great.
Personally, I run stock hexes on my car, and a 1mm plastic wheel shim on all 4 corners just to make it a tick wider all around, and still tuck under the fenders.
Nothing is always.
Everything is sometimes.
