stock rallye wheels small bolt pattern big bolt patter 5x4.5?

very weird....maybe i am mistaken about the stock brakes then. i do have front disc brakes but i could've sworn that when i went outside and measured my lug nut spacing it was 4.5" hmmm I'm confused. anyways the reason i am in a rush to figure this out is bc i am looking to drive up to buy some wheels todays from a private seller. i will just bring a jack and see if it fits on my car right on the spot. just wish i knew if this will be a waste of a drive up there haha
