These very rare and unique 13" x 7 wheels are styled after the early 70's Campagnolo 40802 or the later more common copies - Hayashi Street or Rota Shakotan wheels, but are made by CSA in Australia.
They came on my vintage 70's Honda race car, unfortunately they are not 4x100! They are 4 inch pattern (101.6 mm) and bow the studs on a Honda making it harder to remove and replace the wheels quickly. 4 inch backspacing on wheels. Do your own research on what they will fit... vintage English cars mostly. Wheel center bores are stepped, the largest diameter on the back side is over 2-1/2". I would most likely trade for the same size wheel in 4x100. $350 plus shipping costs or pickup locally. Tires will be removed.
