For anyone wanting to convert the A body from 5x4 over to 5x4.5

I might go with the rallyes though, do you know if the 4 inch back space works?

For the 15x6” rallye’s? Yeah a 4” backspace is fine. The track width of the SBP brakes is narrower, even a 15x7 with a 4” backspace would work.

With the 15x6 the widest you could go would be a 215/65/15 anyway, and with the SBP brakes that would be fine. As long as we’re talking stock SBP brakes and not an aftermarket kit, I didn’t go back and read everything.
