I am thinking about buying the black with red stripe OEM wheels and installing the 8.5 X 20 on all four corners of my 2018 SS convertible. Reasons being the ability to use all season run flats. Does anyone know if there will be fitment or tracking problems by not using the 9.5 X 20 wheels on the rear?

This thread isn’t about your specific wheel interest, but it is a discussion about square setups.

OP just keep the tire height the same as stock front and rear and it will work fine. Keep the offsets similar too. If the height difference is over 3/4-1 inch CE codes will appear. Keeping the stock height will keep your speedo accurate. My LT1 came stock with a winter setup. So keep an eye out for LT1 takeoffs.
