My vision was for the car to have modern looking wheels with 19″ rims and thin tires similiar to a Corvette. A friend has a great set of rims and tires he was willing to sell me that would be perfect. But I quickly ran into problems. Though they were 5 bolt, the bolt pattern was wrong. The Corvair has a 5 bolt 4.75″ pattern and even though these had come off a Pontiac, they were a 410mm. Further checking, and learning turned up that the Corvair suspension is designed for a 4.5″ back spacing and 0 offset. Most cool new rims are 7.5″ back spacing and a 55mm offset. (not sure why offset always seems to be specified in metric and backspacing in inches).

I have looked at wheels that would fit this backspacing and most look vintage. I really would like the wheels to look more modern. They do make adapters but I have heard mixed advice on using these. Though my friends Porsche came from the factory with spacers already installed so they can’t be all bad. But they do have to be machined right.
