What width and brand of tires are most common and work the best? I have found different tires dont all have the same offset and rub my rear pod while others clear with room to spare. Just trying to nail down some loose ends not metioned in setup sheets and get a basic blueprint of how to get my car prepped. THX
See the little hole in the rear of the bottom pod plate? You measure from that center hole in both directions with calipers to equalize the distance to the inner (or outer) side of the wheels. You should have a selection of 1/4" diameter spacers to place on the outer sides of the axle bearings so the axle is centered.
