Drum to Disc Wheel Spacing Change?

Andy Friar · 03-12-2018, 10:56 PM

We are looking to get new rear wheels on our 69 Chevelle to get the tire (Hoosier D07 30 x 9 Bias Ply) more centered in the wheelhouse. Currently we have drums on the car and will for the near future. Eventually we would like to go with discs. My question is have you guys seen much wheel spacing change when swapping from drums to drag style rotors?

Thanks

Find out the thickness of the “hat” for disk brand, subtract thickness of drum = extra stick out of wheel per side. It may change it .187” or so.
